Define interfaces for kubelet pod admission and eviction

There is too much code and logic in `kubelet.go` that makes it hard to test functions in discrete pieces.

I propose an interface that an internal module can implement that will let it make an admission decision for a pod.  If folks are ok with the pattern, I want to move the a) predicate checking, b) out of disk, c) eviction preventing best-effort pods being admitted into their own dedicated handlers that would be easier for us to mock test.  We can then just write tests to ensure that the `Kubelet` calls a call-out, and we can write easier unit tests to ensure that dedicated handlers do the right thing.

The second interface I propose was a `PodEvictor` that is invoked in the main kubelet sync loop to know if pods should be pro-actively evicted from the machine.  The current active deadline check should move into a simple evictor implementation, and I want to plug the out of resource killer code path as an implementation of the same interface.

 @vishh @timothysc - if you guys can ack on this, I will add some unit testing to ensure we do the call-outs.

Avoid allocations and a reflect.Call in conversion

reflect.Call is fairly expensive, performing 8 allocations and having to
set up a call stack. Using a fairly straightforward to generate switch
statement, we can bypass that early in conversion (as long as the
function takes responsibility for invocation). We may also be able to
avoid an allocation for the conversion scope, but not positive yet.

```

kubenet: fix up CNI bridge TX queue length if needed

CNI's bridge plugin mis-handles the TxQLen when creating the bridge,
leading to a zero-length TX queue.  This doesn't typically cause
problems (since virtual interfaces don't have hard queue limits)
but when adding traffic shaping, some qdiscs pull their packet
limits from the TX queue length, leading to a packet limit of 0
in some cases.  Until we can depend on a new enough version of
CNI, fix up the TX queue length internally.

Closes: https://github.com/kubernetes/kubernetes/issues/25092

e2e: Enable persistent volume test

The test is already there and all packages should be already available on all test machines.
    
It tests:

- binding
- using bound claim in a pod
- recycling NFS volume

(we should see shortly if all nfs packages are really installed as Jenkins tests it...)

Remove nodeName from predicate signature.

start etcd compactor in background

ref: #22448

What's in this PR?
- StartCompactor starts a compactor in the background in order to compact keys older than fixed time. We need to compact keys because we can't let on disk data grow forever. We save the most recent 10 minutes data. It should be enough for slow watchers and to tolerate burst. We might keep a longer history (12h) in the future once storage API can take advantage of multi-version key.
- Have only one compaction job for each cluster. Use endpoints from user input to differentiate clusters.

Allow etcd to store protobuf objects

Split storage serialization from client negotiation, and allow API server to take flag controlling serialization.

TODO:

* [x] API server still doesn't start - range allocation object doesn't seem to round trip correctly to etcd
* [ ] Verify that third party resources are ignoring protobuf (add a test)
* [ ] Add integration tests that verify storage is correctly protobuf
* [ ] Add a global default for which storage format to prefer?

Add a better error message to run.sh

I ran build/run.sh w/o any args (by mistake) and it just said
   `Invalid input.`
after several other steps. I had no idea whether I was doing something
wrong or if my env was busted. Clearly, I just forget to include the
command that run.sh was to invoke in the Docker container.  But it took
me time to go track down where this error came from and why. So to help
others I just tweaked the error message to be:
   `Invalid input - please specify a command to run.`

Very minor thing,I know, but if it helps others...
