add generic shared informer backed by existing informer
Adds the ability to get an informer and lister that returns `[]runtime.Object` methods with the "normal" filtering capabilities based on a `GroupResource`. Right now, it only works on known types (and re-uses those caches for efficiency by having a different skin on the `Index`). It should be extended in the future.
@derekwaynecarr I think this gives you the types you were looking for to avoid the ugly array copies.

Support resourceVersion in GetToList - unify interface of List and Ge…
This pretty much unifies the interface of List() and GetToList() methods of storage interface.
I'm going to use it in a subsequent PR to improve performance of the whole cluster.

Return an empty network namespace path for exited infra containers
If the infra container has already terminated, `docker inspect` will report
pid 0. The path constructed using the pid to check the network namespace of
the process will be invalid. This commit changes docker to report an empty
path to stop kubenet from erroring out whenever TearDown is called on an
exited infra container.
This is not a fix for all the plugins, as some plugins may require the actual
network namespace to tear down properly.

Remove last probe time from replica sets
While experimenting with Deployment conditions I found out that if we are going to use lastProbeTime as we are supposed to be using it then we hotloop between updates (see https://github.com/kubernetes/kubernetes/pull/19343#issuecomment-255096778 for more info)

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.
**What this PR does / why we need it**: Overall, improves code structure. Opening single PR in order avoid big PRs in the future, when adding tests and new functionality, i.e. #34404.

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.

Loadbalanced client src ip preservation enters beta
Sounds like we're going to try out the proposal (https://github.com/kubernetes/kubernetes/issues/30819#issuecomment-249877334) for annotations -> fields on just one feature in 1.5 (scheduler). Or do we want to just convert to fields right now?
