Fixed counting of unbound PVCs towards limit of attached volumes.
Count unbound PVCs to the limit of attached volumes to a node.
When MaxPDVolumeCountPredicate is in doubt (e.g. PVC or PV is missing), it assumes the volume is attached. It should assume the same when it encounters an unbound PVC. In any case, it should not return an error, it would stop scheduling all pods with a PVC.

fix broken cloud provider info urls
kubernetes/community repo's commit 3034683c5997474d9f59ef722c8ee9c1f1e58f07
started a re-org of the design-proposals directory to have hierarchical
structure and subdirectories. This in turn broke the urls in the
kubernetes/kubernetes/pkg/cloud-provider/README.md file. This patch adds
the appropriate subdirectories into the urls in the readme.

Add an option for turning on/off compaction from apiserver in etcd3 mode
…erver
**What this PR does / why we need it**:
This commit adds an option for controlling request of compaction to
etcd3 from apiserver. There is a situation that apiserver cannot fully
own its etcd cluster (e.g. sharing it with canal). In such a case,
apiserver should have limited access in terms of etcd's auth
functionality so it don't have a privilege to issue compaction
requests. It means that the compaction requests should be issued by
other component and apiserver's compaction requests are needless.
For such use cases, this commit adds a new flag
storagebackend.Config.DoCompaction. If the flag is true (default),
apiserver issues the compaction requests like current behaviour. If it
is false, apiserver doesn't issue the requests.
**Related issue (etcd)**

Disable autoscaling before removing autoscaled node pool
This is to prevent flakes due to API calls failing in AfterEach during master restart, which is triggered by deleting an autoscaled node pool. Adding disable call before deleting node pool should prevent this as we'll wait for master restart in disableAutoscaler function.
While it may be faster to wait after deletion of autoscaled node pools, this is less complex and will be easier to remove in the future when changing autoscaling setttings no longer triggers master restart.

Implement CRI stats in Docker Shim
**What this PR does / why we need it**:
This PR implements CRI Stats in the Docker Shim. It is needed to enable CRI stats for Docker and ongoing /stats/summary API changes in moving to use CRI.
Related issues:
#46984 (CRI: instruct kubelet to (optionally) consume container stats from CRI)
#45614 (CRI: add methods for container stats)
This PR is also a followup to my original PR (https://github.com/kubernetes/kubernetes/pull/50396) to implement Windows Container Stats. The plan is that Windows Stats will use a hybrid model: pod and container level stats will come from CRI (via dockershim) and that node level stats will come from a "winstats" package that exports cadvisor like datastructures using windows specific perf counters from the node. I will update that PR to only export node level stats.
