Provide flags to use etcd3 backed storage

ref: #24405

What's in this PR?
- Add a new flag "storage-backend" to choose "etcd2" or "etcd3". By default (i.e. empty), it's "etcd2".
- Take out etcd config code into a standalone package and let it create etcd2 or etcd3 storage backend given user input.

Bump up etcd dependency to fix data race

ref: https://github.com/kubernetes/kubernetes/pull/23694

What this PR does
- Bumping up the godep of etcd to fix data race in etcd watcher. Without this change, watcher PR builds will fail in race detection.
- Small changes to fix builds after upgrade

Automatic merge from submit-queue

Make etcd cache size configurable

Instead of the prior 50K limit, allow users to specify a more sensible size for their cluster.

I'm not sure what a sensible default is here. I'm still experimenting on my own clusters. 50 gives me a 270MB max footprint. 50K caused my apiserver to run out of memory as it exceeded >2GB. I believe that number is far too large for most people's use cases.

There are some other fundamental issues that I'm not addressing here:
- Old etcd items are cached and potentially never removed (it stores using modifiedIndex, and doesn't remove the old object when it gets updated)
- Cache isn't LRU, so there's no guarantee the cache remains hot. This makes its performance difficult to predict. More of an issue with a smaller cache size.
- 1.2 etcd entries seem to have a larger memory footprint (I never had an issue in 1.1, even though this cache existed there). I suspect that's due to image lists on the node status.

This is provided as a fix for #23323

Daniel Smith c0ffbd58db Remove TestWatchEtcdError 
We decided to remove this test, as there's no way to get an upper bound
on its running time. Etcd restart behavior should be tested in
integration or e2e tests.
