Map a resource to multiple signals in eviction manager
It is possible to have multiple signals that point to the same type of
resource, e.g., both SignalNodeFsAvailable and
SignalAllocatableNodeFsAvailable refer to the same resource NodeFs.
Change the map from map[v1.ResourceName]evictionapi.Signal to
map[v1.ResourceName][]evictionapi.Signal

PodSecurityPolicy.allowedCapabilities: add support for * to allow to request any capabilities
**What this PR does / why we need it**:
Prior this change there was no way to allow to pods to request any capabilities. Cluster admin had always specify a full list of capabilities explicitly. Because there are many of them, it gets tedious. This PR makes possible to use `*` to allow all possible capabilities. Non-paranoid (and lazy) cluster admins can use it. Those who are super strict and paranoid of course won't use it because `*` allows capabilities that don't exist today but may be introduced in the future.
"privileged" PSP in examples was modified to allow privileged users to use this feature.

In cluster size autoscaling tests, use allocatable instead of capacity for node memory
This makes cluster size autoscaling e2e tests use node allocatable resources when computing how much memory we need to consume in order to trigger scale up/prevent scale down. It should fix failing tests in GKE.

Eliminate hangs/throttling of node heartbeat
Fixes https://github.com/kubernetes/kubernetes/issues/48638Fixes#50304
Stops kubelet from wedging when updating node status if unable to establish tcp connection.
Notes that this only affects the node status loop. The pod sync loop would still hang until the dead TCP connections timed out, so more work is needed to keep the sync loop responsive in the face of network issues, but this change lets existing pods coast without the node controller trying to evict them
```release-note
kubelet to master communication when doing node status updates now has a timeout to prevent indefinite hangs

Add cluster-name option for cloud controller manager
**What this PR does / why we need it**:
`cluster-name` is used by servicecontroller and routecontroller, for controller-manager, we have a parameter to set it, but for cloud-controller-manager, it will always be of default value 'kubernetes'.
An example of impact is Azure's loadbalancer, the loadbalancer resource created will always have the name 'kubernetes', while it used to be the cluster name set via controller manger's option.

Increase sliding window to 5hr for request_latencies metric
We're seeing high latency values for a couple of types of api calls in our density test (ref https://github.com/kubernetes/kubernetes/issues/51899). And we're recording values from only the last 1 hour in the metric (as @wojtek-t told me offline) - so our test result is pretty much counting only the calls during the delete phase.
