use LC_ALL=C on all sort commands
Most of these don't matter, but this makes it predicable no matter who runs the commands.

Optimize label selector
The number of values for a given label is generally pretty small (in huge majority of cases it is exactly one value).
Currently computing selectors is up to 50% of CPU usage in both apiserver and scheduler.
Changing the structure in which those values are stored from map to slice improves the performance of typical usecase for computing selectors.
Early results:
- scheduler throughput it ~15% higher
- apiserver cpu-usage is also lower (seems to be also ~10-15%)

kubeadm: Normalized reset command to match init and join commands.

Add `--mounter-path` flag to kubelet that will allow overriding the `mount` command used by kubelet
In order to be able to use new mounter library, this PR adds the
mounterPath flag to kubelet which passes the flag to the mount
interface. If flag is empty, mount uses default mount path.

move proxytransport config out of the genericapiserver
Proxy transport is not generic. This moves it to the master config where it is used.
Lots of places used sort (or sort -u) but didn't set LC_ALL=C. This
means it could be slightly different on different people's systems. Make
it deterministic.

Fix a bug under the rkt runtime whereby image-registries with ports would not be fetched from
```
This fixes a bug whereby an image reference that included a port was not
recognized after being downloaded, and so could not be run
This is the quick-and-simple fix. In the longer term, we'll want to refactor image logic a bit more to handle the many special cases that the current code does not, mostly related to library images on dockerhub.

Predicate cacheing and cleanup
Fix to #31795
First pass @ cleanup and caching of the CheckServiceAffinity function.
The cleanup IMO is necessary because the logic around the pod listing and the use of the "implicit selector" (which is reverse engineered to enable the homogenous pod groups).
Should still pass the E2Es.

If token validation fails, give the user the expected format.
If a user specifies their own token to kubeadm, and it fails validation, the error they currently receive isn't the friendliest. This first change adds messaging for the expected token format, with more improvements to follow as part of #33930. It also adds some unit tests to document the behavior we have currently.

Add secret e2e test for keys mapping
**What this PR does / why we need it**: Adds a basic e2e test missing in secrets
**Which issue this PR fixes** *(optional, in `fixes #<issue number>(, #<issue_number>, ...)` format, will close that issue when PR gets merged)*:
**Special notes for your reviewer**:
**Release note**:
```NONE
```
This patch adds a secret e2e test. While configmap e2e tests are far
more complete, this patch makes secret e2e tests one step closer.
Also, now is more easy to add more tests without code duplication (as I
did in earlier patches :-/), because of the functions created, and is
more easy to make it similar to confimap e2e in the future, that is
really complete.
