Add launching Cluster Autoscaler in Kubemark
**What this PR does / why we need it**:
Allows to launch Cluster Autoscaler in Kubemark.
To do it, set ENABLE_KUBEMARK_CLUSTER_AUTOSCALER flag to true. This currently only works with one nodegroup, for which you can specify minimum and maximum number of nodes and name. (KUBEMARK_AUTOSCALER_MIN_NODES, KUBEMARK_AUTOSCALER_MAX_NODES, KUBEMARK_AUTOSCALER_MIG_NAME).
Is is important to note that NUM_NODES has a different meaning when launching Cluster Autoscaler - we always start with only one node, but NUM_NODES is used to calculate the size of Kubemark master and addon components.
There are no changes to the current setup if ENABLE_KUBEMARK_CLUSTER_AUTOSCALER is set to false.

Fix the defaultServerImage name of hyperkube in kubefed
**What this PR does / why we need it**:
Fixes the issue mentioned in https://github.com/kubernetes/kubernetes/issues/53430
Docker images cannot contain special characters like '+' in the tags. So while uploading the federation container images we replace '+' character by '_'. This should have been taken care by kubefed too while consuming the federation container image.
**Which issue this PR fixes** *(optional, in `fixes #<issue number>(, fixes #<issue_number>, ...)` format, will close that issue when PR gets merged)*: fixes#53430
**Special notes for your reviewer**:
This PR fixes the "invalid reference format" issue for the docker image. But am not sure if the version of hyperkube image is available in registry. The version is got from `version.Get()`. So if a user has built the kubefed from source it may be possible that the hyperkube version referenced by that commit is not available in registry. Ideally this issue should not arise on released versions of kubefed.
We need to cherry-pick this fix to all previous supported k8s versions too.

```release-note
NONE

Clarify predicates name to clean confusing
**What this PR does / why we need it**:
Just make the scheduling message more clear.
by reading the message described in https://github.com/kubernetes/kubernetes/issues/52166 for several times, i recognize that from user's view our indication indeed exist a little confusing. I think our scheduling message is more from view of developer, but not user's view. Since predicates want to filter nodes to get the fit nodes. In this case, the fit nodes are nodes no under memory pressure. And `NodeUnderDiskPressure` has the same problem.

Skip e2e check for logs API path if provider is skeleton
There is a networking e2e test with the It() description:
```
"should provide unchanging, static URL paths for kubernetes api services"
```
This test performs GETs from the Kubernetes API using various paths,
including "/logs". This test for a GET using path "/logs" should be
skipped for provider type "skeleton", since this path is unsupported.
This change adds "skeleton" to the list of providers for which
this test case should be skipped.
fixes#53529
**What this PR does / why we need it**:
This change adds "skeleton" to the list of providers for which
the test for an API GET using the "/logs" path should be skipped.
This is needed because, as far as I can tell, the "skeleton" provider
doesn't support the "/logs" api path.
