Add PriorityClass API object under new "scheduling" API group
**What this PR does / why we need it**: This PR is a part of a series of PRs to add pod priority to Kubernetes. This PR adds a new API group called "scheduling" with a new API object called "PriorityClass". PriorityClass maps the string value of priority to its integer value.
**Which issue this PR fixes** *(optional, in `fixes #<issue number>(, fixes #<issue_number>, ...)` format, will close that issue when PR gets merged)*: fixes #
**Special notes for your reviewer**: Given the size of this PR, I will add the admission controller for the PriorityClass in a separate PR.
**Release note**:
```release-note

Return clusterErr rather than err
The updateClusterIngressUIDToMasters() should return clusterErr, not err.
If the 'err' of 'masterCluster, masterUID, err := ic.getMasterCluster()' is nil and the 'clusterErr' of 'clusterObj, clusterErr := api.Scheme.DeepCopy(cluster)' is not nil, updateClusterIngressUIDToMasters() will return ("", nil).
And do not log fallbackUID when fallbackUID is nil.

incluster config will be used when creating external shared informers.
**What this PR does / why we need it**:
Previously the loopback configuration was used to talk to the server.
As a consequence a custom API server was unable to talk to the root API server.
This PR changes the above by using incluster configuration to create shared informers.

Add a spin-loop that waits for RBAC API's availability.
The very first thing that kubefed does when it comes up is run RBAC API discovery. We believe this sometimes fail on new clusters and as a result causes kubefed to assume that the RBAC API doesn't exist. Therefore, we are applying this workaround for now to ensure that the RBAC API is available before running kubefed.
