Uniform Azure VM api calls
**What this PR does / why we need it**:
There is still a call to 'VirtualMachinesClient.Get' directly in azure_backoff, which does not go through the cache approach.
This PR uniforms all calls for getting azure vm to use 'getVirtualMachine'. Also refine unused 'exists' return value.

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.

Optimizing the implementation of the error check for PriorityClass
**What this PR does / why we need it**:
When i create pod(on the bottom) with not exist PriorityClass, the output will be shown as follow:
```
# kubectl apply -f priorityclassname-pod.yaml
Error from server: error when creating "priorityclassname-pod.yaml": failed to get default priority class not-exist-priorityclassname: priorityclass.scheduling.k8s.io "not-exist-priorityclassname" not found
```
In my eyes, "get default priority class" is not the correct description, so i changed it. The new output will be shown like this:
```
# kubectl apply -f priorityclassname-pod.yaml
Error from server (NotFound): error when creating "priorityclassname-pod.yaml": priorityclass.scheduling.k8s.io "not-exist-priorityclassname" not found
```
In addition, the 'pc' will never be nil when err is nil, i think this check is not neccessary, so i removed it.
thank you!

Move DefaultMaxEBSVolumes constant into scheduler
**What this PR does / why we need it**:

periodically check whether assigned kubelet config should become last-known-good
Fixes#57808
Previously, the last-known-good was only updated on Kubelet restart. This has been on my todo list for a while, good to finally have a PR up.
Previously we could have this scenario, which is fixed by this PR:
- lkg is set to local
- we set config A
- config A passes trial period, but nothing caused Kubelet to restart
- we set config B, which turns out to be invalid
- Kubelet will fall back to local, because lkg was never updated
