Federated replica set pod analyser
A helper function that analyses a list of pods and checks how many of them (per cluster) are running or are unschedulable.
This function should be replaced by a smarter/more effective informer that would count these values on the fly. Unfortunately this needs the ownerRef feature which may not be ready/enabled in 1.4.
WIP because tests are not there yet. Will be added in the evening (PL time).

OpenAPI / Swagger2 spec generation
This is alpha version of OpenAPI spec generation. Generated "/swagger.json" file (accessible on api server) is a valid OpenAPI spec with some warnings that will be fixed in next versions of spec generation. Currently it is possible to generate a client using this spec though I did not test the clients.
reference: #13414
**Release note**:
```release-note
Alpha support for OpenAPI (aka. Swagger 2.0) specification serves on /swagger.json
```

Fix memory leak in gc
ref #30759
GC had a memory leak. The work queue item is never deleted.
I'm still fighting with my kubemark cluster to get statistics after this fix.

ClusterAutoscaler-friendly scheduler priority function that promotes well-used nodes
It will help cluster autoscaler to put pods on nodes that are unlikely to be deleted soon due to low usage. Otherwise a pod may be frequently kicked from one node to another. A flag that enables it when CA is on will be added in a separate PR.
Fixes: #28842

Disable linux/ppc64le compilation by default
Work-around for #30384.
I'm still testing this locally to see if it actually works. The build is slow. (PR Jenkins won't tell us whether this fixes ppc.)

extract common function in ingress and federation e2e to uil
Separate refactoring existing e2e code part from #29773
1. extract common constants, structs and functions in federated-service.go to federation-util.go, move existing util functions from federated-service.go to federation-util.go
2. extract common constants, structs and functions in ingress.go to ingress-util.go, move existing util functions from ingress.go to ingress-util.go

Node E2E: Make readiness check handling process exits with 0 exit code.
As is mentioned by @mtaufen:
"there is a problem with the way service `start` is currently implemented in test/e2e_node/e2e_service.go. If the Kubelet exits with status 0 before the health check completes, cmdErrorChan will be closed and, as a result, nil will be read from that channel, and you will return a nil error from `start`."
This PR changes the logic to:
1) If the err channel returns an error, return the error
2) If the err channel returns a nil, ignore it and continue checking readiness.
3) If the err channel is closed before readiness check succeeds, replace it with `blockCh` and continue checking readiness.

Move UTs that block on apiserver to integration tests.
In validating etcd.v3client we had uncovered that a change in the behavior of the client https://github.com/coreos/etcd/issues/6162 , caused a number of unit tests to fail. These test failures were due to the fact that the unit tests were trying to standup a apiserver even though there was no etcd backend stood up.
This PR simply shuffles those tests to integration tests, which is where they should be.

This mirrors a similar side fix for the API server authenticator.
Don't trim the issuer URL provided by the user since OpenID Connect
mandates that this URL exactly matches the URL returned by the
issuer during discovery.
Not test updates since this is already tested by the go-oidc client
package.

Add GUBERNATOR flag which produces g8r link for node e2e tests
When you run 'make tests-e2e-node REMOTE=true GUBERNATOR=true' outputs a URL to view the test results on Gubernator. ~~Should work after my PR for Gubernator is merged.~~
