Current logic would assume all the NVMe disks are data disks and
applicable for reformat and mount. This will cause the issue when
booting disk is also NVMe disk, which will fail the node boot up. This
change will check if any additional NVMe disks are required/specified
and skip the reformat step otherwise.
An etcd unix user is currently created in configure-helper.sh if it does not exist
on the master.
cloud-init is the only supported mechanism to add users on COS VMs. If an attempt
is made to add a key using OS Login or the instance metadata mechanism the
google_accounts_daemon will race with useradd and potentially attempt to use
the same UID. This will lock out any attempt to SSH into the VM. We therefore
migrate to using cloud-init to create this user and prevent this issue from occurring.
If we don't install docker and install just containerd apt packages,
there is no docker group. In this scenario, we should not add the gid to
config.toml

This commit adds support for using `gke-exec-auth-plugin` (vTPM-based
certificates for mTLS) for webhooks when calling endpoints matching
`*.googleapis.com`, and integrates this support with
ValidatingAdmissionWebhook.
To enable it, request ValidatingAdmissionWebhook with
`ADMISSION_CONTROL=...,ValidatingAdmissionWebhook,...` (default) and
opt in to `gke-exec-auth-plugin` using `WEBHOOK_GKE_EXEC_AUTH=true`
during the configuration process.
If you don't opt-in, ValidatingAdmissionWebhook will be deployed as
before.
Requesting `WEBHOOK_GKE_EXEC_AUTH=true` will fail if you have not
provided other configuration variables:
* `EXEC_AUTH_PLUGIN_URL`: controls whether `gke-exec-auth-plugin` is
downloaded during the installation step. A prerequisite for
actually using the plugin.
* `TOKEN_URL`, `TOKEN_BODY`, and `TOKEN_BODY_UNQUOTED`:
configuration values used when calling the plugin. `TOKEN_URL`
and `TOKEN_BODY` have existing usage. `TOKEN_BODY_UNQUOTED` is a
new variable that is meant to sidestep the problem of inverting
`strconv.Quote` in Bash.
The existing configuration process for ImagePolicyWebhook has been
reworked to make it play nicely with ValidatingAdmissionWebhook under
`WEBHOOK_GKE_EXEC_AUTH=true`.
* It originally placed the ImagePolicyWebhook configuration object
at the top-level of the file specified by
`--admission-control-config-file`. I can't see why this worked;
it must have been hitting some sort of lucky path through the
various config file loading mechanisms. Now, it places its
configuration in a sub-field of that file, which is shared among
all admission control plugins.
* It mounted its various config files read-write. I reviewed the
code and couldn't see why it was necessary, so I moved the config
files into the existing read-only mount at `/etc/srv/kubernetes`.
* It now checks that all the configuration values it requires have
been provided.

Split arguments to be passed to cluster autoscaler binary,
so each argument is passed separately.
This is preparatory work for migrating CA to disroless base image
and passing multiple arguments together does not work if CA is
not wrapped around with shell script

This change renames the '--experimental-encryption-provider-config'
flag to '--encryption-provider-config'. The old flag is accepted but
generates a warning.
In 1.14, we will drop support for '--experimental-encryption-provider-config'
entirely.

This change includes the yaml files and gce startup script changes
to run this addon. It is disabled by default, can be enabled by setting
KUBE_ENABLE_NODELOCAL_DNS=true
An ip address is required for the cache instance to listen for
requests on, default is a link local ip address of value 169.254.25.10
addressed review comments, updated image location
Picked a different prometheus port so stats port is not same as the
coredns deployment
Removed the nodelocaldns-ready label.

Remove e2e-image-puller
**What this PR does / why we need it**:
A long time ago, We added the image prepulling as a workaround due to
the overwhelming amount of flake caused by pulling during the tests.
This functionality has been broken for a while now when we switched to a
COS image where mounting `docker` binary into `busybox` stopped working.
So we just have dead code we should clean up.

In the context, our urandoms where generally safe, however getrandom has
built in invariants around entropy pool initialization, making getrandom
safe in all contexts. This should protect us from cryptopasta errors or
weird entropy issues.

Support extra prune resources in kube-addon-manager.
The default prune whitelist resources in https://github.com/kubernetes/kubernetes/blob/master/pkg/kubectl/cmd/apply.go#L531 are sometimes not enough.
One example is that when we remove an admission webhook running as an addon pod, after we remove the addon yaml file, the admission webhook pod will be pruned, but the `MutatingWebhookConfiguration`/`ValidationWebhookConfiguration` won't... If the webhook failure policy is `Fail`, this will break the cluster, and users can't create new pods anymore.
It would be good to at least make this configurable, so that users and vendors can configure it based on their requirement.
This PR keeps the default prune resource list exactly the same with before, just makes it possible to add extra ones.

The requested Service Protocol is checked against the supported protocols of GCE Internal LB. The supported protocols are TCP and UDP.
SCTP is not supported by OpenStack LBaaS. If SCTP is requested in a Service with type=LoadBalancer, the request is rejected. Comment style is also corrected.
SCTP is not allowed for LoadBalancer Service and for HostPort. Kube-proxy can be configured not to start listening on the host port for SCTP: see the new SCTPUserSpaceNode parameter
changed the vendor github.com/nokia/sctp to github.com/ishidawataru/sctp. I.e. from now on we use the upstream version.
netexec.go compilation fixed. Various test cases fixed
SCTP related conformance tests removed. Netexec's pod definition and Dockerfile are updated to expose the new SCTP port(8082)
SCTP related e2e test cases are removed as the e2e test systems do not support SCTP
sctp related firewall config is removed from cluster/gce/util.sh. Variable name sctp_addr is corrected to sctpAddr in pkg/proxy/ipvs/proxier.go
cluster/gce/util.sh is copied from master
Implemented the call to get all cluster objects in a zone for a project.
Also added code to allow the container api to be set in the gce.conf
file.
Requested fix for @lavalamp. Fixed GetClusters to be GetManagedClusters.
Leaving ListClusters as ListClusters as it is part of the Cloud Clusters
interface, despite also being a "managed" call.
Remove copy pasta :D

Metadata Agent Improvements
Bump metadata agent version to 0.2-0.0.21-1.
Expand the metadata agent's access to all API groups.
Remove metadata agent config maps in favor of command line flags.
Update the metadata agent's liveness probe to a new /healthz handler.
Logging Agent Improvements
Bump logging agent version to 0.2-1.5.33-1-k8s-1.
Appropriately set log severity for k8s_container.
Fix detect exceptions plugin to analyze message field instead of log field.
Fix detect exceptions plugin to analyze streams based on local resource id.
Disable the metadata agent for monitored resource construction in logging.
Disable timestamp adjustment in logs to optimize performance.
Reduce logging agent buffer chunk limit to 512k to optimize performance.
In addition to the shell script changes the heapster yaml has been
updated to use addon resizer 1.8.3 for the heapster-nanny. Addon resizer 1.8.3
is being used to take advantage of the new minClusterSize flag. Note this is a
no-op change. The values specified for heapster-nanny reflect the current
configuration used with version 1.8.2.
