Instead of just rate limits to operation polling, send all API calls
through a rate limited RoundTripper.
This isn't a perfect solution, since the QPS is obviously getting
split between different controllers, etc., but it's also spread across
different APIs, which, in practice, rate limit differently.
Fixes#26119 (hopefully)

Handle federated service name lookups in kube-dns.
For the domain name queries that fail to match any records in the local
kube-dns cache, we check if the queried name matches the federation
pattern. If it does, we send a CNAME response to the federated name.
For more details look at the comments in the code.
Tests are coming ...
Also, this PR is based on @ArtfulCoder's PR #23930. So please review only the last commit here.

cache: reflector should never stop watching
A recent change tries to separate resync and relist. The motivation
was to avoid triggering relist when a resync is required.
However, the change is not effective since it stops the watcher. As hongchao
mentioned in the original comment, today's storage interface will not deliever
any progress notification to the watch chan. So any watcher that does not receive
events for the last few seconds will not be able to catch up from the previous
index after a hard close since the index of the last received event is out of
the cache window inside etcd2.
This pull request tries to fix this issue by not stoping watcher when a resync is
required.
