Move kubelet flag generation from the node to the client
Pass the kubelet flags through a new variable in kube-env (KUBELET_ARGS).
Remove vars from kube-env that were only used for kubelet flags.
This will make it simpler to gradually migrate to dynamic kubelet
config, because we can gradually replace flags with config file
options in a single place without worrying about the plumbing to
move variables from the client onto the node.

Add code and yaml for Istio as an addon
This commit adds the following:
- YAML for istio components to the addons directory (versions with
and without auth)
- logic to copy the appropriate YAML file into the addons manager
dir, depending on ENABLE_ISTIO and ISTIO_AUTH_TYPE env vars
- changes to addon manager script which allow plugins to exist in
namespace other than kube-system. This is needed for Istio
functionality
- additional initialization for Istio in addon manager.
This has been manually tested - e2e tests are in progress but require additional code to enable istio in tests. See:
- https://github.com/istio/istio/pull/2841
- https://github.com/kubernetes/test-infra/pull/6612
**What this PR does / why we need it**:
Allow [Istio](https://istio.io/) to be installed as an addon. This simplifies the Istio setup process on k8s and GKE. Istio team is trying to make it easier for end users to get to a basic functional installation.

Add a new environment variable to the gce startup scripts called KUBE_PROXY_MODE
**What this PR does / why we need it**:
This PR adds a new environment variable called KUBE_PROXY_MODE to the startup scripts for gce. This variable will allow a user to specify the kube-proxy implementation they want to use, with the choices being ipvs or iptables (iptables is default).
Next steps:
1. Need to remove use of feature gateway when IPVS goes GA
2. Need to add logic of loading required ipvs kernel modules in the scripts
Question: If the proxier is IPVS, is it necessary to have the iptables sync period flags?
**Release note**:
```release-note

This is the 2nd attempt. The previous was reverted while we figured out
the regional mirrors (oops).
New plan: k8s.gcr.io is a read-only facade that auto-detects your source
region (us, eu, or asia for now) and pulls from the closest. To publish
an image, push k8s-staging.gcr.io and it will be synced to the regionals
automatically (similar to today). For now the staging is an alias to
gcr.io/google_containers (the legacy URL).
When we move off of google-owned projects (working on it), then we just
do a one-time sync, and change the google-internal config, and nobody
outside should notice.
We can, in parallel, change the auto-sync into a manual sync - send a PR
to "promote" something from staging, and a bot activates it. Nice and
visible, easy to keep track of.

a deprecated feature.
* fix build, release, deploy to look for everything in its new home
- If REMOUNT_VOLUME_PLUGIN_DIR is set to true, VOLUME_PLUGIN_DIR is remounted with `exec` option during cluster startup. This allows any writable location to be used as the plugin directory.
- New HostPath added to controller-manager deployment to enable access to volume plugin directory.
- Improved how the default directory is passed to master and node setup.

Add options for mounting SCSI or NVMe local SSD though Block or Filesystem and do all of that with UUID
Fixes: #51431
Fixed version of: #53466
Mount SCSI local SSD by UUID in /mnt/disks/by-uuid/, also allows for users to request and mount NVMe disks. Both types of disks will be accessible either through block or file-system.
I have confirmed that it is no longer crashing when nodes are initialized on GKE.
Lack of this flag sometimes causes iptables to return error code 4 (if
other process holds xtables lock). As a result, because of `set -o errexit`,
whole startup script fails, leaving master in an incorrect state.

Run nvidia-gpu device-plugin daemonset as an addon on GCE nodes that have nvidia GPUs attached
- Instead of the old `Accelerators` feature that added `alpha.kubernetes.io/nvidia-gpu` resource, use the new `DevicePlugins` feature that adds vendor specific resources. (In case of nvidia GPUs it will
add `nvidia.com/gpu` resource.)
- Add node label to GCE nodes with accelerators attached. This node label is the same as what GKE attaches to node pools with accelerators attached. (For example, for nvidia-tesla-p100 GPU, the label would be `cloud.google.com/gke-accelerator=nvidia-tesla-p100`) This will help us target accelerator specific
daemonsets etc. to these nodes.
- Run nvidia-gpu device-plugin daemonset as an addon on GCE nodes that have nvidia GPUs attached.
- Some minor documentation improvements in addon manager.
**Release note**:
```release-note
GCE nodes with NVIDIA GPUs attached now expose `nvidia.com/gpu` as a resource instead of `alpha.kubernetes.io/nvidia-gpu`.

Remove Google Cloud KMS's in-tree integration
Removes the following introduced by #48574 and others:
* `kms.go` which contained the cloudkms-specific code for Google Cloud KMS service.
* Registering the Google Cloud KMS in the KMS plugin registry.
* Google's `cloudkms` API package from `vendor` folder.
The following changes are upcoming:
* Removal of KMSPluginRegistry. This would not be needed anymore, since KMS providers will be out-of-tree from now on (so no need of registering them, an address of the process would be enough).
* A service which allows encrypt/decrypt functionality (satisfies `envelope.Service` interface) if initialized with an IP/Port of an out-of-tree process serving KMS requests. Will tentatively use gRPC requests to talk to this external service.
Reference: https://github.com/kubernetes/kubernetes/pull/54439#issuecomment-340062801 and https://github.com/kubernetes/kubernetes/issues/51965#issuecomment-339333937.
```release-note
Google KMS integration was removed from in-tree in favor of a out-of-process extension point that will be used for all KMS providers.

Add support to for alternative container runtime in `kube-up.sh`
For https://github.com/kubernetes/features/issues/286.
This PR added 4 new environment variables in `kube-up.sh` to support alternative container runtime:
1) `KUBE_MASTER_EXTRA_METADATA` and `KUBE_NODE_EXTRA_METADATA`. Add extra metadata on master and node instance. With this we could specify different cloud-init for a different container runtime, and also add extra metadata for the new cloud-init, e.g. [master.yaml](7d73966214/test/e2e/master.yaml)
2) `KUBE_CONTAINER_RUNTIME_ENDPOINT`. Specify different sock for different container runtime. It's only used when it's not empty.
3) `KUBE_LOAD_IMAGE_COMMAND`. Specify different load image command for different container runtime.
An example for cri-containerd:
```
export KUBE_MASTER_EXTRA_METADATA="user-data=${GOPATH}/src/github.com/kubernetes-incubator/cri-containerd/test/e2e/master.yaml,cri-containerd-configure-sh=${GOPATH}/src/github.com/kubernetes-incubator/cri-containerd/test/configure.sh"
export KUBE_NODE_EXTRA_METADATA="user-data=${GOPATH}/src/github.com/kubernetes-incubator/cri-containerd/test/e2e/node.yaml,cri-containerd-configure-sh=${GOPATH}/src/github.com/kubernetes-incubator/cri-containerd/test/configure.sh"
export KUBE_CONTAINER_RUNTIME="remote"
export KUBE_CONTAINER_RUNTIME_ENDPOINT="/var/run/cri-containerd.sock"
export KUBE_LOAD_IMAGE_COMMAND="/home/cri-containerd/usr/local/bin/cri-containerd load"
export NETWORK_POLICY_PROVIDER="calico"

This allows the etcd docker registry that is currently hard coded to
`gcr.io/google_containers/etcd` in the `etcd.manifest` template to be
overridden. This can be used to test new versions of etcd with
kubernetes that have not yet been published to
`gcr.io/google_containers/etcd` and also enables cluster operators to
manage the etcd images used by their cluster in an internal
repository.

Allow enable pod priority feature gate for GCE and configure priority for kube-proxy
**What this PR does / why we need it**:
From #23225, this PR adds an option for user to enable pod priority feature gate using GCE startup scripts, and configure pod priority for kube-proxy when enabled.
The setup `priorityClassName: system` derives from: ce1485c626/staging/src/k8s.io/api/core/v1/types.go (L2536-L2542)
The plan is to configure pod priority for kube-proxy daemonset (https://github.com/kubernetes/kubernetes/pull/50705) in the same way.

FlexVolume setup script for COS instance using mounting utility image in GCR.
**What this PR does / why we need it**: This scripts automates FlexVolume installation for a single COS instance. Users need to pre-pack their drivers and mount utilities in a Docker image and upload it to GCR.
For each FlexVolume plugin, the script places a driver wrapper in a writable and executable location. The wrapper calls commands from the actual driver but in a chroot environment, so that mount utilities from the image can be used.
I'm working on a script that automatically executes this on all instances. Will be in a separate PR.
