Add metrics to all major gce operations (latency, errors)
```release-note
Add metrics to all major gce operations {latency, errors}
The new metrics are:
cloudprovider_gce_api_request_duration_seconds{request, region, zone}
cloudprovider_gce_api_request_errors{request, region, zone}
`request` is the specific function that is used.
`region` is the target region (Will be "<n/a>" if not applicable)
`zone` is the target zone (Will be "<n/a>" if not applicable)
Note: this fixes some issues with the previous implementation of
metrics for disks:
- Time duration tracked was of the initial API call, not the entire
operation.
- Metrics label tuple would have resulted in many independent
histograms stored, one for each disk. (Did not aggregate well).

Use provided VipPortID for OpenStack LB
**What this PR does / why we need it**:
When creating an OpenStack LoadBalancer, Kubernetes will search through the tenant trying to match the LB's VIP with a port. This is problematic because multiple ports may have the same fixed IP, therefore leading to routing inconsistencies. We should use the port ID provided by the LB's response body instead.
**Which issue this PR fixes**:
https://github.com/kubernetes/kubernetes/issues/43909
**Special notes for your reviewer**:
Since this involves non-deterministic testing, it'd be best if we can run this in a staging environment for a few days before merging (say until early next week).

Implement LRU for AWS device allocator
On failure to attach do not use device from pool
In AWS environment when attach fails on the node
lets not use device from the pool. This makes sure
that a bigger pool of devices is available.
I changed the function signature to contain protocol, port, and path.
When the service has a health check path and port set it will create an
HTTP health check that corresponds to the port and path. If those are
not set it will create a standard TCP health check on the first port
from the listeners that is not nil. As far as I know, there is no way to
tell if a Health Check should be HTTP vs HTTPS.

Add support for Azure internal load balancer
**Which issue this PR fixes**
Fixes https://github.com/kubernetes/kubernetes/issues/38901
**What this PR does / why we need it**:
This PR is to add support for Azure internal load balancer
Currently when exposing a serivce with LoadBalancer type, Azure provider would assume that it requires a public load balancer.
Thus it will request a public IP address resource, and expose the service via that public IP.
In this case we're not able to apply private IP addresses (within the cluster virtual network) for the service.
**Special notes for your reviewer**:
1. Clarification:
a. 'LoadBalancer' refers to an option for 'type' field under ServiceSpec. See https://kubernetes.io/docs/resources-reference/v1.5/#servicespec-v1
b. 'Azure LoadBalancer' refers a type of Azure resource. See https://docs.microsoft.com/en-us/azure/load-balancer/load-balancer-overview
2. For a single Azure LoadBalancer, all frontend ip should reference either a subnet or publicIpAddress, which means that it could be either an Internet facing load balancer or an internal one.
For current provider, it would create an Azure LoadBalancer with generated '${loadBalancerName}' for all services with 'LoadBalancer' type.
This PR introduces name '${loadBalancerName}-internal' for a separate Azure Load Balancer resource, used by all the service that requires internal load balancers.
3. This PR introduces a new annotation for the internal load balancer type behaviour:
a. When the annotaion value is set to 'false' or not set, it falls back to the original behaviour, assuming that user is requesting a public load balancer;
b. When the annotaion value is set to 'true', the following rule applies depending on 'loadBalancerIP' field on ServiceSpec:
- If 'loadBalancerIP' is not set, it will create a load balancer rule with dynamic assigned frontend IP under the cluster subnet;
- If 'loadBalancerIP' is set, it will create a load balancer rule with the frontend IP set to the given value. If the given value is not valid, that is, it does not falls into the cluster subnet range, then the creation will fail.
4. Users may change the load balancer type by applying the annotation to the service at runtime.
In this case, the load balancer rule would need to be 'switched' between the internal one and external one.
For example, it we have a service with internal load balancer, and then user removes the annotation, making it to a public one. Before we creating rules in the public Azure LoadBalancer, we'll need to clean up rules in the internal Azure LoadBalancer.

# Adds CloudAllocator to the node CIDR allocator (kubernetes-controller manager).
If CIDRAllocatorType is set to `CloudCIDRAllocator`, then allocation

- Splits off the rangeAllocator from the cidr_allocator.go file.
- Adds cloudCIDRAllocator, which is used when the cloud provider allocates
the CIDR ranges externally. (GCE support only)

Remove the dependency of login information on worker nodes for vsphere cloud provider:
1. VM Name is required to be set in the cloud provider configuration file.
2. Remove the requirement of login for Instance functions when querying local node information.
The cloudprovider is being refactored out of kubernetes core. This is being
done by moving all the cloud-specific calls from kube-apiserver, kubelet and
kube-controller-manager into a separately maintained binary(by vendors) called
cloud-controller-manager. The Kubelet relies on the cloudprovider to detect information
about the node that it is running on. Some of the cloudproviders worked by
querying local information to obtain this information. In the new world of things,
local information cannot be relied on, since cloud-controller-manager will not
run on every node. Only one active instance of it will be run in the cluster.
Today, all calls to the cloudprovider are based on the nodename. Nodenames are
unqiue within the kubernetes cluster, but generally not unique within the cloud.
This model of addressing nodes by nodename will not work in the future because
local services cannot be queried to uniquely identify a node in the cloud. Therefore,
I propose that we perform all cloudprovider calls based on ProviderID. This ID is
a unique identifier for identifying a node on an external database (such as
the instanceID in aws cloud).

VSAN policy support for storage volume provisioning inside kubernetes
The vsphere users will have the ability to specify custom Virtual SAN Storage Capabilities during dynamic volume provisioning. You can now define storage requirements, such as performance and availability, in the form of storage capabilities during dynamic volume provisioning. The storage capability requirements are converted into a Virtual SAN policy which are then pushed down to the Virtual SAN layer when a storage volume (virtual disk) is being created. The virtual disk is distributed across the Virtual SAN datastore to meet the requirements.
For example, User creates a storage class with VSAN storage capabilities:
> kind: StorageClass
> apiVersion: storage.k8s.io/v1beta1
> metadata:
> name: slow
> provisioner: kubernetes.io/vsphere-volume
> parameters:
> hostFailuresToTolerate: "2"
> diskStripes: "1"
> cacheReservation: "20"
> datastore: VSANDatastore
The vSphere Cloud provider provisions a virtual disk (VMDK) on VSAN with the policy configured to the disk.
When you know storage requirements of your application that is being deployed on a container, you can specify these storage capabilities when you create a storage class inside Kubernetes.

Fix for Support selection of datastore for dynamic provisioning in vS…
Fixes#40558
Current vSphere Cloud provider doesn't allow a user to select a datastore for dynamic provisioning. All the volumes are created in default datastore provided by the user in the global vsphere configuration file.
With this fix, the user will be able to provide the datastore in the storage class definition. This will allow the volumes to be created in the datastore specified by the user in the storage class definition. This field is optional. If no datastore is specified, the volume will be created in the default datastore specified in the global config file.
For example:
User creates a storage class with the datastore
kind: StorageClass
apiVersion: storage.k8s.io/v1beta1
metadata:
name: slow
provisioner: kubernetes.io/vsphere-volume
parameters:
diskformat: thin
datastore: VMFSDatastore
Now the volume will be created in the datastore - "VMFSDatastore" specified by the user.
If the user creates a storage class without any datastore
kind: StorageClass
apiVersion: storage.k8s.io/v1beta1
metadata:
name: slow
provisioner: kubernetes.io/vsphere-volume
parameters:
diskformat: thin
Now the volume will be created in the datastore which in the global configuration file (vsphere.conf)

Update Photon Controller cloud provider for authentication support
Resolve Issue: [#40755](https://github.com/kubernetes/kubernetes/issues/40755)
1. Update the configuration file for Photon Controller cloud provider
2. Only master nodes can communicate with Photon Controller endpoint
3. Enable support for authentication-enabled Photon Controller endpoint
4. Update NodeAddresses function for query from local node
New format of photon controller config file:
```
[Global]
target = https://[LOAD_BALANCER_IP]:443
project = [PROJECT ID]
overrideIP = true
vmID = [LOCAL VM ID]
authentication = true
```
This config file will be automatically created by Photon Controller cluster management.
If authentication file is set to true, then a pc_login_info file should be placed under /etc/kubernetes with username and password.
This file can be created by user directly.
Or the user can choose to use kubernetes secret and a handling pod to avoid directly login to master nodes. This usage will be available with Photon Controller 1.2.
This is a temporary solution before metadata service becomes available in Photon Controller.

Test is to verify diskformat specified in storage-class is being honored while volume creation.
Steps:
1. Create StorageClass with diskformat set to valid type (supported options are `eagerzeroedthick`, `zeroedthick` and `thin`)
2. Create PVC which uses the StorageClass created in step 1.
3. Wait for PV to be provisioned.
4. Wait for PVC's status to become Bound
5. Create POD using PVC on specific node.
6. Wait for Disk to be attached to the node.
7. Get node VM's devices and find PV's Volume Disk.
8. Get Backing Info of the Volume Disk and obtain Property of `VirtualDiskFlatVer2BackingInfo` - `EagerlyScrub` and `ThinProvisioned`

Fix AWS device allocator to only use valid device names
According to
http://docs.aws.amazon.com/AWSEC2/latest/UserGuide/device_naming.html
we can only use /dev/xvd[b-c][a-z] as device names - so we can only
allocate upto 52 ebs volumes on a node.

In cases where insecure OpenStack endpoint is to be used
(e.g., when testing), gophercloud will fail to connect
to such endpoints. This patch adds support for custom CA
file configuration option, which, when provided, will

Fixes#40819 and Fixes#33114
**What this PR does / why we need it**:
Start looking up the virtual machine by it's UUID in vSphere again. Looking up by IP address is problematic and can either not return a VM entirely, or could return the wrong VM.
Retrieves the VM's UUID in one of two methods - either by a `vm-uuid` entry in the cloud config file on the VM, or via sysfs. The sysfs route requires root access, but restores the previous functionality.
Multiple VMs in a vCenter cluster can share an IP address - for example, if you have multiple VM networks, but they're all isolated and use the same address range. Additionally, flannel network address ranges can overlap.
vSphere seems to have a limitation of reporting no more than 16 interfaces from a virtual machine, so it's possible that the IP address list on a VM is completely untrustworthy anyhow - it can either be empty (because the 16 interfaces it found were veth interfaces with no IP address), or it can report the flannel IP.

Fix for detach volume when node is not present/ powered off
Fixes#33061
When a vm is reported as no longer present in cloud provider and is deleted by node controller, there are no attempts to detach respective volumes. For example, if a VM is powered off or paused, and pods are migrated to other nodes. In the case of vSphere, the VM cannot be started again because the VM still holds mount points to volumes that are now mounted to other VMs.
In order to re-join this node again, you will have to manually detach these volumes from the powered off vm before starting it.
The current fix will make sure the mount points are deleted when the VM is powered off. Since all the mount points are deleted, the VM can be powered on again.
This is a workaround proposal only. I still don't see the kubernetes issuing a detach request to the vsphere cloud provider which should be the case. (Details in original issue #33061 )

Adding vmdk file extension for vmDiskPath in vsphere DeleteVolume
**What this PR does / why we need it**:
This fix is required to handle situation when volume path is not set with vmdk file extension.
DiskAttach call does not require vmdk file extension to be explicitly set in the file path, so in PV yaml file, users have option to set such file path.

In an effort to expand the existing pool of reviewers and establish a
two-tiered review process (first someone lgtms and then someone
experienced in the project approves), we are adding new reviewers to
existing owners files.
If You Care About the Process:
------------------------------
We did this by algorithmically figuring out who’s contributed code to
the project and in what directories. Unfortunately, that doesn’t work
well: people that have made mechanical code changes (e.g change the
copyright header across all directories) end up as reviewers in lots of
places.
Instead of using pure commit data, we generated an excessively large
list of reviewers and pruned based on all time commit data, recent
commit data and review data (number of PRs commented on).
At this point we have a decent list of reviewers, but it needs one last
pass for fine tuning.
Also, see https://github.com/kubernetes/contrib/issues/1389.
TLDR:
-----
As an owner of a sig/directory and a leader of the project, here’s what
we need from you:
1. Use PR https://github.com/kubernetes/kubernetes/pull/35715 as an example.
2. The pull-request is made editable, please edit the `OWNERS` file to
remove the names of people that shouldn't be reviewing code in the
future in the **reviewers** section. You probably do NOT need to modify
the **approvers** section. Names asre sorted by relevance, using some
secret statistics.
3. Notify me if you want some OWNERS file to be removed. Being an
approver or reviewer of a parent directory makes you a reviewer/approver
of the subdirectories too, so not all OWNERS files may be necessary.
4. Please use ALIAS if you want to use the same list of people over and
over again (don't hesitate to ask me for help, or use the pull-request
above as an example)

AWS: Remove duplicate calls to DescribeInstance during volume operations

AWS: Add exponential backoff to waitForAttachmentStatus() and createTags()
We should use exponential backoff while waiting for a volume to get attached/detached to/from a node. This will lower AWS load and reduce API call throttling.
This partly fixes#33088
@justinsb, can you please take a look?
GCE PD names generated by Kubernetes are guaranteed to be unique - they
contain name of the cluster and UID of the PVC that is behind it.
Presence of a GCE PD that has the same name as we want to provision
indicates that previous provisioning did not go well and most probably
the controller manager process was restarted in the meantime.
Kubernetes should reuse this volume and not provision a new one.

AWS: Add sequential allocator for device names.
On AWS, we should not reuse device names as long as possible, see https://aws.amazon.com/premiumsupport/knowledge-center/ebs-stuck-attaching/
> "If you specify a device name that is not in use by EC2, but is being used by the block device driver within the EC2 instance, the attachment of the EBS volume does not succeed and the EBS volume is stuck in the attaching state."
This patch adds a device name allocator that tries to find a name that's next to the last used device name instead of using the first available one. This way we will loop through all device names ("xvdba" .. "xvdzz") before a device name is reused.

Remove Azure Subnet RouteTable check
**What this PR does / why we need it**:
PR Removes the subnet configuration check for Azure cloudprovider. The subnet check ensures that the subnet is associated with the Route Table. However if the VNET is in a different Azure Resource Group then the check fails, even if the subnet is already valid.

Bad conditional in vSphereLogin function
```release-note
Fixes NotAuthenticated errors that appear in the kubelet and kube-controller-manager due to never logging in to vSphere
```
With this conditional being == instead of !=, a login would never actually be attempted by this provider, and disk attachments would fail with a NotAuthenticated error from vSphere.
This method has been unused by k8s for some time, and yet is the last
piece of the cloud provider API that encourages provider names to be
human-friendly strings (this method applies a regex to instance names).
Actually removing this deprecated method is part of a long effort to
migrate from instance names to instance IDs in at least the OpenStack
provider plugin.

Fixes#36880
This change implements the Routes API using Neutron's "extraroute"
extension.
To use, this requires all the nodes to be on the same Neutron network
and the UUID of the Neutron router on that network.
Required cloud provider config section:
[Route]
router-id = <UUID of Neutron router>
Ensure kube-controllermanager is started with (non-default)
`--allocate-node-cidrs=true` and set `--cluster-cidr` to the POD
super-subnet (a private /16 would be reasonable).
Based on an earlier version by @timbyr (#19473)
Update EnsureLoadBalancer/UpdateLoadBalancer API to use node objects.
In particular, this allows us to take the node address directly from the
node.Status.Addresses and avoids a name -> instance lookup.
Many providers need to do some sort of node name -> IP or instanceID
lookup before they can use the list of hostnames passed to
EnsureLoadBalancer/UpdateLoadBalancer.
This change just passes the full Node object instead of simply the node
name, allowing providers to use the node's provider ID and cached
addresses without additional lookups. Using `node.Name` reproduces the
old behaviour.
