Cleanup non-rest apiserver handlers
- rename MuxHelper -> PathRecorderMux
- move non-rest handlers into routes packages within genericapiserver and `pkg/routes` (those from master)
- move ui and logs handlers out of genericapiserver (they are
not generic)
- make version handler configurable (`config.EnableVersion`)

Switch ScheduledJob controller to use clientset

Add the uid in a delete event to the absentOwnerCache
This is a small optimization to further reduce the traffic sent by the GC.
In #31167, GC caches the non-existent owners when it processes the dirtyQueue. As discovered in #32571, there is still small inefficiency, because there are multiple goroutines processing the dirtyQueue, many of them might send a GET to the apiserver before the cache gets populated.
This PR populates the cache when GC observes an object gets deleted, which happens before the processing of the dirtyQueue, so it avoids the simultaneous GET sent by the GC workers.

Specific error message on failed rolling update issued by older kubectl against 1.4 master
Fix#32706
`kubernetes-e2e-gke-1.4-1.3-kubectl-skew` (1.3 kubectl and 1.4 master) test suite failed with:
```
k8s.io] Kubectl client [k8s.io] Kubectl rolling-update should support rolling-update to same image [Conformance]
...
Error from server: object is being deleted: replicationcontrollers "e2e-test-nginx-rc" already exists error: exit status 1 not to have occurred
```
It's because the old RC had an orphanFinalizer, so it is not deleted from the key-value store immediately. In turn, the creation of the new RC of the same name failed.
In this failure, the RC and pods are updated, it's just that the RC is of different name, i.e., original name + a hash generated based on podTemplate. The error is confusing to user, but not that bad. So this PR just prints a warning message to instruct users how to work around.
1.4 kubectl rolling-update uses different logic so it's working.

Handle Stream() errors consistently in restclient
We should be following the same rules for Stream() as the normal body
request flow.
Also add slightly more output on a server error - in the future we may
want to clean this up but it's potentially hiding bad responses.
Related to #32009 but isn't the fix (so far)
