pkg/api: extract Scheme/Registry/Codecs into pkg/api/legacyscheme

This serves as

- a preparation for the pkg/api->pkg/apis/core move
- and makes the dependency to the scheme explicit when vizualizing
  left depenncies.

The later helps with our our efforts to split up the monolithic repo
into self-contained sub-repos, e.g. for kubectl, controller-manager
and kube-apiserver in the future.

Michail Kargakis af0f5dcc88
Fix deployment timeout reporting
If the previous condition has been a successful rollout then we
shouldn't try to estimate any progress. Scenario:

* progressDeadlineSeconds is smaller than the difference between
  now and the time the last rollout finished in the past.
* the creation of a new ReplicaSet triggers a resync of the
  Deployment prior to the cached copy of the Deployment getting
  updated with the status.condition that indicates the creation
   of the new ReplicaSet.

The Deployment will be resynced and eventually its Progressing
condition will catch up with the state of the world.

make deployment unit tests need to respect subresources

Fixes #42569
I check all the unit test code related to `Matches` method, seems there's only one line we could change to not break previous testing logic

Update deployment retries to a saner count

It seems that the current retries sum up to no more than 0.2s so some transient errors may drop deployments out of the queue.

I noticed this when running kube-scheduler with --v4 and it is annoying.

Anthony Yeh 0b9233648e Deflake TestSyncDeploymentDeletionRace
The cache was sometimes catching up while we were testing the case
where the cache is not yet caught up.

Before this fix, I could reproduce the failure with the following
command. After the fix, it passes.

```
go test -count 100000 -run TestSyncDeploymentDeletionRace

GC: Fix re-adoption race when orphaning dependents.

**What this PR does / why we need it**:

The GC expects that once it sees a controller with a non-nil
DeletionTimestamp, that controller will not attempt any adoption.
There was a known race condition that could cause a controller to
re-adopt something orphaned by the GC, because the controller is using a
cached value of its own spec from before DeletionTimestamp was set.

This fixes that race by doing an uncached quorum read of the controller
spec just before the first adoption attempt. It's important that this
read occurs after listing potential orphans. Note that this uncached
read is skipped if no adoptions are attempted (i.e. at steady state).

**Which issue this PR fixes**:

Fixes #42639

**Special notes for your reviewer**:

Automatic merge from submit-queue

kubectl: Use v1.5-compatible ownership logic when listing dependents.

**What this PR does / why we need it**:

This restores compatibility between kubectl 1.6 and clusters running Kubernetes 1.5.x. It introduces transitional ownership logic in which the client considers ControllerRef when it exists, but does not require it to exist.

If we were to ignore ControllerRef altogether (pre-1.6 client behavior), we would introduce a new failure mode in v1.6 because controllers that used to get stuck due to selector overlap will now make progress. For example, that means when reaping ReplicaSets of an overlapping Deployment, we would risk deleting ReplicaSets belonging to a different Deployment that we aren't about to delete.

This transitional logic avoids such surprises in 1.6 clusters, and does no worse than kubectl 1.5 did in 1.5 clusters. To prevent this when kubectl 1.5 is used against 1.6 clusters, we can cherrypick this change.

**Which issue this PR fixes**:

Fixes #43159
