Fix node e2e issues on selinux enabled systems
It fixes following 3 node e2es:
```
[Fail] [k8s.io] Container Runtime Conformance Test container runtime conformance blackbox test when starting a container that exits [It] it should run with the expected status [Conformance]
/root/upstream-code/gocode/src/k8s.io/kubernetes/test/e2e_node/runtime_conformance_test.go:114
[Fail] [k8s.io] Kubelet metrics api when querying /stats/summary [It] it should report resource usage through the stats api
/root/upstream-code/gocode/src/k8s.io/kubernetes/test/e2e_node/kubelet_test.go:158
```
```
[Fail] [k8s.io] Container Runtime Conformance Test container runtime conformance blackbox test when starting a container that exits [It] should report termination message if TerminationMessagePath is set [Conformance]

allow handler to join after the informer has started
This allows an event handler to join after a SharedInformer has started. It can't add any indexes, but it can add its reaction functions.
This works by
1. stopping the flow of events from the reflector (thus stopping updates to our store)
1. registering the new handler
1. sending synthetic "add" events to the new handler only
1. unblocking the flow of events
It would be possible to
1. block
1. list
1. add recorder
1. unblock
1. play list to as-yet unregistered handler
1. block
1. remove recorder
1. play recording
1. add new handler
1. unblock
But that is considerably more complicated. I'd rather not start there since this ought to be the exception rather than the rule.
@wojtek-t who requested this power in the initial review
@smarterclayton @liggitt I think this resolves our all-in-one ordering problem.

"Mover" should be "Moreover"
In file docs/proposals/apiserver-watch.md, line #108, "Mover, this will not require any changes in other parts of the code.", here "Mover" should be "Moreover".

dedup workqueue requeuing
Updates `workqueue.AddAfter` to only perform the add for the earliest requested requeue operation. An earlier time inserts in the earlier slot and removes the old one. A later time is ignored.
When using this conjunction with an `AddRateLimited` method, you get charged for the additional retry even though you're only queue once.
This keeps requeues from multiplying for every add.

Fix logic of consecutive DELETE calls when gracefull deletion is enabled
Previously it was possible to extend delete timestamp to infinity by issuing repeated DELETE calls. This PR prevents that. Ref. discussion in #27422

cacher: replace usable lock with conditional variable
Perviously we use a rwlock to indicate the ready information of the cacher. I feel it is not straightforward. Also it requires a few comments to explain. The pull request tries to replace the lock with a conditional variable for readability reason.

e2e: increase timeout when waiting for deployment pods to be deleted
Use the same timeout as the one used for waiting for the deployment
reaper to complete.

Unify DeleteAllEtcdKeys in integration tests & start using namespaces in some tests
Getting rid of DeleteAllEtcdKeys() and running all tests in separate namespace is necessary to run integration tests in parallel.
Aside from that, this is first step of reducing amount of annoying logs in integration tests...

WIP - Handle map[]struct{} in DeepCopy
Deep copy was not properly handling the empty struct case we use for Sets.
@lavalamp I need your expertise when you have some time - the go2idl parser is turning sets.String into the following tree:
type: sets.String kind: Alias
underlying: map[string]sets.Empty kind: Map
key: string kind: Builtin
elem: set.Empty kind: Struct
^
should be Alias
Looking at tc.Named, I'm not sure what the expected outcome would be and why you flatten there.

Make generated build tag parameterizable for go2idl
Downstream generators that want to reuse the upstream generated types
need to be able to define a different ignore tag (so that they can see
the already generated types).
@wojtek-t allows third parties to reuse conversions in api/v1 (for instance) because otherwise they are hidden when go2idl parses the dependency packages.

Cleanup a TODO from godeps -> vendor change
This logs a false "error" message, so it's time to go. It was needed to ensure
nobody has stale build images laying around, but that was quite a while ago, so
it's probably safe now.

kubectl: ignore only update conflicts in the scaler
@kubernetes/kubectl is there any reason to retry any other errors?
While testing this fix in OpenShift it was discovered that the
PackageConstraint was overly aggressive - types that declare a public
copy function should always return true. PackageConstraint is intended
to limit packages where we might generate deep copy function, rather
than to prevent external packages from being consumed.

need to be able to define a different ignore tag (so that they can see

Make validators return error strings
Part of the larger validation PR, broken out for easier review and merge. Builds on previous PRs in the series. This is a group of smaller commits, so I don't waster precious PR numbers.
