The azure cloudprovider will now use the Managed Service Identity
to retrieve access tokens for the Azure ARM APIs, rather than
requiring hard-coded, user-specified credentials.
Currently, client-go requires that an IPv6 address string for hostname has
square brackets surrounding, so that it can be used with address:port in
an API request.
This change, removes that requirement, and has getListener() add the
square brackets for IPv6 addresses for hosts. If IPv4 or hostname, the name
will not be modified.
Decided to change here, rather than everywhere client-go is used (thinking
that there may be places where we DON'T want the square brackets applied).
This issue was found in kubelet, which, at startup, creates a listener for
services and nodes. If an IPv6 address is used, the URI was malformed.
This PR fixes the following issues:
1. Use ResourceStorageScratch instead of ResourceStorage API to represent
local storage capacity
2. In eviction manager, use container manager instead of node provider
(kubelet) to retrieve the node capacity and reserved resources. Node
provider (kubelet) has a feature gate so that storagescratch information
may not be exposed if feature gate is not set. On the other hand,
container manager has all the capacity and allocatable resource
information.
This behavior regressed in an earlier release. Clearing the self link
ensures that a new version is always written and reduces the size of the
stored object by a small amount. Add tests to verify that Create and
Update result in no SelfLink stored in etcd.

Fix subPath existence check to not follow symlink
**What this PR does / why we need it**:
Volume mounting logic introduced in #43775 and #45623 checks
for subPath existence before attempting to create a directory,
should subPath not be present.
This breaks if subPath is a dangling symlink, os.Stat returns
"do not exist" status, yet `os.MkdirAll` can't create directory
as symlink is present at the given path.
This patch makes existence check to use os.Lstat which works for
normal files/directories as well as doesn't not attempt to follow
symlink, therefore it's "do not exist" status is more reliable when
making a decision whether to create directory or not.
subPath symlinks can be dangling in situations where kubelet is
running in a container itself with access to docker socket, such
as CoreOS's kubelet-wrapper script
**Release note**:
```release-note
Fix pods failing to start when subPath is a dangling symlink from kubelet point of view, which can happen if it is running inside a container
