Endpoints can add a get or connect options type in their group
optionsExternalVersion is being used for shared types (meta.k8s.io). The
installer should first look in the current API group for GET and CONNECT
options objects before checking in `v1`.
OpenShift hit this while registering a new connect handler endpoint in an api group for an api that is aggregated. OpenShift should not be registering its API types into the core API group.

Improve PVC ref volume metric test robustness
This test has been flaking. The current working theory is that
volume stats collection didn't run in time to grab the metrics
from the newly created pod.
Made the following changes:
- Added more logs to help debug future failures
- Poll metrics a few additional times before failing the test

Add a label which prevents a node from being added to a cloud load balancer
There are a variety of reasons that you may not want a node in a cluster to participate in a cloud load balancer. For example workload isolation for security, or managing network throughput, or because the node is not in the appropriate virtual network (cluster's that span environments)
This PR adds a label so that you can select which nodes you want to participate.

Normalize RepoTags before checking for match
**What this PR does / why we need it**:
on projectatomic-based docker, we get "docker.io/library/busybox:latest"
when someone uses an unqualified name like "busybox". Though when we
inspect, the RepoTag will still say "docker.io/busybox:latest", So
we have reparse the tag, normalize it and try again. Please see the
additional test case.

federation/pkg/federation-controller/util: fix swallowed errors
**What this PR does / why we need it**: The re-declaration of `err` inside the `if` block causes it to be lost before the check on line 93, even though it is reassigned on lines 95 and 90. By declaring the secret variable on line 71 I was able to ditch the `:=` assignment on line 72, meaning we can keep the `err` variable previously defined before the block on line 47.

Simplify deployment in federation CI jobs
**What this PR does / why we need it**:
Introduce a new variable `USE_PV_FOR_ETCD` to control whether to use PV for federation etcd. `USE_PV_FOR_ETCD` is set to false by default and can be overridden in CI jobs where we want to test with PV. For most of the federation CI jobs, it does not matter whether we use PV for etcd or not. We can overcome some issues by not depending on PV's in federation setup like failure to bind to PV and leaking PD's. etc...
#50543 is one such issue associated with PV.
This PR also contain a commit to fix couple of minor issues and removing unnecessary include of cluster/common script.
