Add AUTOSCALER_ENV_VARS to kube-env to hotfix cluster autoscaler
This provides a temporary way for the cluster autoscaler to get at
values that were removed from kube-env in #60020. Ideally this
information will eventually be available via e.g. the Cluster API,
because kube-env is an internal interface that carries no stability
guarantees.
This is the first half of the fix; the other half is that cluster autoscaler
needs to be modified to read from AUTOSCALER_ENV_VARS, if it is
available.
Since cluster autoscaler was also reading KUBELET_TEST_ARGS for the
kube-reserved flag, and we don't want to resurrect KUBELET_TEST_ARGS in kube-env,
we opted to create AUTOSCALER_ENV_VARS instead of just adding back
the old env vars. This also makes it clear that we have an ugly dependency
on kube-env.

Bump to etcd 3.1.12 to pick up critical fix
etcd [3.1.12](https://github.com/coreos/etcd/releases/tag/v3.1.12) (as well as 3.2.17 and 3.3.2) was released yesterday to fix a bug critical to kubernetes:
Fix [mvcc "unsynced" watcher restore operation](https://github.com/coreos/etcd/pull/9297).
- "unsynced" watcher is watcher that needs to be in sync with events that have happened.
- That is, "unsynced" watcher is the slow watcher that was requested on old revision.
- "unsynced" watcher restore operation was not correctly populating its underlying watcher group.
- Which possibly causes [missing events from "unsynced" watchers](https://github.com/coreos/etcd/issues/9086).
This will be backported to 1.9 as well.
Release note:
```release-note
Upgrade the default etcd server version to 3.1.12 to pick up critical etcd "mvcc "unsynced" watcher restore operation" fix.

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

GCE: Create cloud-provider roles and bindings via addons
**What this PR does / why we need it**:
This removes the `cloud-provider` role and role binding from the rbac boostrapper and replaces it with a policy applied via addon mgr. This also creates a new clusterrole allowing the service account to create events for any namespace.
**Special notes for your reviewer**:

**Release note**:
```release-note
GCE: A role and clusterrole will now be provided with GCE/GKE for allowing the cloud-provider to post warning events on all services and watching configmaps in the kube-system namespace.
```
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.

juju: Fix broken ingress after upgrade-charm
**What this PR does / why we need it**:
This fixes a bug that prevents the ingress controller from being deployed after doing an `upgrade-charm`.
Essentially, `worker.auth.bootstrapped` gets cleared during `upgrade-charm`, and it never gets set again. This prevents the `start_worker` and `render_and_launch_ingress` handlers from running, among other things.
This PR fixes that.

Add etcd 3.x minor version rollback support to migrate-if-needed.sh
Provide automatic etcd 3.x minor version downgrade when using the gcr.io/google_containers/etcd docker images to operate etcd.
Uses `etcdctl snapshot save` and `etcdctl snapshot restore` to safely downgrade etcd from 3.2->3.1 or 3.1->3.0. This is safe because the data storage file formats used by etcd have not changed between these versions.
Intended as a stop-gap until we can introduce more comprehensive downgrade support in etcd. The main limitation of this approach is that it is not able to perform zero downtime downgrades for HA clusters. For HA clusters, all members must be stopped and downgraded before the cluster may be restarted at the downgraded version.
Example usage:
- Initially the [etcd.manifest](58547ebd72/cluster/gce/manifests/etcd.manifest (L43)) is set to gcr.io/google_containers/etcd:3.0.17, TARGET_VERSION=3.0.17
- A upgrade to 3.1.11 is initiated.
- etcd.manifest is updated to gcr.io/google_containers/etcd:3.1.11, TARGET_VERSION=3.1.11
- etcd restarts and establishes 3.1 as it's "cluster version"
- For whatever reason, a downgrade is initiated
- etcd.manifest is updated gcr.io/google_containers/etcd:3.1.11, TARGET_VERSION=3.0.17
- migrate-if-needed.sh detects that the current version (3.1.11) is newer than the target version, so it:
- creates a snapshot using etcd & etcdctl 3.1.11
- backs up the data dir
- restores the snapshot using etcdctl 3.0.17 to create a replacement data dir
- starts etcd 3.0.17
Note that while this will rollback to an earlier etcd version, the newer etcd gcr.io image version must continue to be used throughout the downgrade. Only TARGET_VERSION is downgraded.
Test coverage was lacking for `migrate-if-needed.sh` so this adds some container level testing to the `Makefile` for migrating and rolling back. This surfaced a couple bugs that are fixed by this PR as well.

2nd try at using a vanity GCR name
The 2nd commit here is the changes relative to the reverted PR. Please focus review attention on that.
This is the 2nd attempt. The previous try (#57573) 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.
xref https://github.com/kubernetes/release/issues/281
TL;DR:
* The new `staging-k8s.gcr.io` is where we push images. It is literally an alias to `gcr.io/google_containers` (the existing repo) and is hosted in the US.
* The contents of `staging-k8s.gcr.io` are automatically synced to `{asia,eu,us)-k8s.gcr.io`.
* The new `k8s.gcr.io` will be a read-only alias to whichever regional repo is closest to you.
* In the future, images will be promoted from `staging` to regional "prod" more explicitly and auditably.
```release-note
Use "k8s.gcr.io" for pulling container images rather than "gcr.io/google_containers". Images are already synced, so this should not impact anyone materially.
Documentation and tools should all convert to the new name. Users should take note of this in case they see this new name in the system.
```

Make kubelet flags of kube-up.sh configurable.
Fixes https://github.com/kubernetes/kubernetes/issues/59503.
For CRI container runtime, we need to pass kubelet the container runtime cgroup.
~~Currently, for `e2e-up.sh` we can use `KUBE_TEST_ARGS` to configure kubelet flags. However, for `kube-up.sh` we don't have a way to configure it.~~
Actually we can also use `KUBE_TEST_ARGS` for kubelet flags. However, I prefer we still make this change to make the env name more formalized.

Previous commit relied on non-obvious reactive behavior, with the
'docker.restart' flag being exploited to re-execute docker_logins_changed
in a single hook execution.
Split this into 2 handlers:
- when docker-logins config changes, set one flag to handle the login
and another to request a daemon restart (if needed).
- run docker login after any potential daemon restarts have occurred.

Ensure that the runtime mounts RO volumes read-only
**What this PR does / why we need it**:
This change makes it so that containers cannot write to secret, configMap, downwardAPI and projected volumes since the runtime will now mount them read-only. This change makes things less confusing for a user since any attempt to update a secret volume will result in an error rather than a successful change followed by a revert by the kubelet when the volume next syncs.
It also adds a feature gate `ReadOnlyAPIDataVolumes` to a provide a way to disable the new behavior in 1.10, but for 1.11, the new behavior will become non-optional.
Also, E2E tests for downwardAPI and projected volumes are updated to mount the volumes somewhere other than /etc.

Fixes#58719
**Release note**:
```release-note

container modifications to files in these types of volumes were temporary and reverted by the kubelet

preserve the old behavior.

Forcing get_node_name to continue searching for a node name.
There was a race condition where the kubelet was restarting and we were querying the api server for this node. In that case, we may get a valid list of nodes that doesn't include our node. This would cause the code to just raise an exception. Now we wait the full timeout before raising the exception.

Fix master regex when running multiple clusters
**What this PR does / why we need it**:
I'm running two Kubernetes clusters on GCE. One for production and one for staging. The instance prefix I use for production is `kubernetes` and for staging it's `staging-kubernetes`. This caused a problem when running `kube-up.sh` for production because when it tries to find all instances which match `kubernetes(-...)?` it finds both the production and staging instances. This probably results in multiple problems, but the most noticeable one for me was that `INITIAL_ETCD_CLUSTER` was incorrect and so etcd wouldn't start up correctly so the api server doesn't start up correctly so nothing else starts up. I tested this manually and it seems to work for me, but I didn't write an automated test.

Quality of life fix. We used to set an RC to run the nginx ingress and then scale it in the charm as workers were added. Now we just use a daemon set to make sure it is running everywhere. Using application-specific names and roles so multiple applications can have different ingress settings.

Honor make variable OUT_DIR in hyperkube Makefile
Needed to ensure the split of `make cross-in-a-container` and `make package-tarballs` honors the use of `OUT_DIR`.
In the new and upcoming containerized (GCB) release builds, multiple `cross-in-a-container` targets are run into their own `_output ($OUT_DIR)` directories and a second pass runs multiple `package-tarballs`.
This won't work unless we honor `$OUT_DIR` here.

Add 'exec' in all saltbase manifests using '/bin/sh -c'.
Right now, if docker sends SIGTERM, /bin/sh doesn't pass it to
underlying process, which breaks graceful process shutdown.
Changing '/bin/sh -c CMD > /var/log/FILE.log' pattern to '/bin/sh -c
exec CMD > /var/log/FILE.log' still allows to redirect output to log
file, but also passes all signals to CMD process.
