[Kubelet] Fix race condition in container manager
**What this PR does / why we need it**:
This fixes a race condition where the container manager capacity map was being updated without synchronization. It moves the storage capacity detection to kubelet initialization, which happens serially in one thread.

Ensures node becomes schedulable at the end of tests that delete nodes
**What this PR does / why we need it**: Further fixes the flakiness of "Pod Disk should be able to detach from a node which was deleted". When a node becomes ready but not schedulable, it was not included in the final node count.
**Which issue this PR fixes** *(optional, in `fixes #<issue number>(, fixes #<issue_number>, ...)` format, will close that issue when PR gets merged)*: fixes#48008
**Special notes for your reviewer**: Updated a similar test, "Pod Disk should be able to detach from a node whose api object was deleted", to use an "Expect" instead of a soft error because the test needs to guarantee that the environment is *completely* reset.
**Release note**:
```release-note-none

cmd/create_deployment: refactor long function
Refactor the `createDeployment` function under `pkg/kubectl/cmd`.
- [x] Behavior has been extracted to two helper functions.
- [x] Behavior remains identical.
- [x] Logic has been made explicit through function naming and comments.
This is essentially the pattern I've been following in my larger branches (the ones that are pending the merge of #46468). Want to get some design feedback before I get too far away from `master`.
Thanks!

Add a failsafe for etcd not returning a connection string
**What this PR does / why we need it**: Removing a kubernetes-master will fail as described on this issue: https://github.com/juju-solutions/bundle-canonical-kubernetes/issues/311

**Special notes for your reviewer**: This is a two liner defensive code. I am not totally sold on this patch. I might not be the right place to address the above issue. However, solving the problem on the etcd side and updating the interface scope to be unit (as suggested) seems much more involving.

Use endpoints informer for the endpoint controller
This substantially reduces the number of API calls made by the endpoint
controller. Currently the controller makes an API call per endpoint for
each service that is synced. When the 30s resync is triggered, this
results in an API call for every single endpoint in the cluster. This
quickly exceeds the default qps/burst limit of 20/30 even in small
clusters, leading to delays in endpoint updates.
This change modifies the controller to use the endpoint informer cache
for all endpoint GETs. This means we only make API calls for changes in
endpoints. As a result, qps only depends on the pod activity in the
cluster, rather than the number of services.
**What this PR does / why we need it**:
Address endpoint update delays as described in https://github.com/kubernetes/kubernetes/issues/47597.
