Automatically add system critical priority classes at cluster boostrapping
**What this PR does / why we need it**:
We had two PriorityClasses that were hardcoded and special cased in our code base. These two priority classes never existed in API server. Priority admission controller had code to resolve these two names. This PR removes the hardcoded PriorityClasses and adds code to create these PriorityClasses automatically when API server starts.

code-gen: output golint compliant 'Generated by' comment
New PR instead of reopening #58115 because /reopen did not work.
This won't be ready to merge until the upstream https://github.com/kubernetes/gengo/pull/94 merges. Once that merges, the second commit will be changed to godep-save.sh and update-staging-godeps.sh, and the last commit will be changed to update-all.sh
The failing test is due to the upstream changes not being merged yet
```devel-release-note
Go code generated by the code generators will now have a comment which allows them to be easily identified by golint

Move `storageclass` into `storage` package under `plugin/pkg/admission`
We have two directories `storage` and `storageclass` under package `plugin/pkg/admission` and one subdir `storageobjectinuseprotection` of `storage` now.
- 1. Move `storageclass` into `storage` being `storage`'s sub-package since storageclass is one of the storage objects
- 2. fix golint failures

Critical pod priorityClass addition
**What this PR does / why we need it**:
@bsalamat - Apologies for the delay. This PR is to ensure that all pods with priorityClassName `system-node-critical` and `system-cluster-critical` will be critical pods while preserving backwards compatibility.
**Special notes for your reviewer**:
- Moved some constants and other data structures to scheduler/api/types.go where other constants are present.
- An automatic assignment of critical priorities to pods based on critical pod annotation for backwards compatibility including some unit tests.
