Change minion to node

Continuation of #1111

I tried to keep this PR down to just a simple search-n-replace to keep
things simple.  I may have gone too far in some spots but its easy to
roll those back if needed - just let me know.

I avoided renaming `contrib/mesos/pkg/minion` because there's already
a `contrib/mesos/pkg/node` dir and fixing that will require a bit of work
due to a circular import chain that pops up. So I'm saving that for a
follow-on PR.

Rewrite summary e2e test to check metric sanity

Take two, forked from https://github.com/kubernetes/kubernetes/pull/28195

Adds a test library that extends the ginkgo matchers to check nested data structures. Then uses the new matcher library to thoroughly check the validity of every field in the summary metrics API. This approach is more flexible than the previous approach since it allows for different tests per-field, and is easier to add case-by-case exceptions. It also places the lower & upper bounds side-by-side, making the test much easier to read & reason about.

Most fields are expected to be within some bounds. This is not intended to be a performance test, so metric bounds are very loose. Rather, I'm looking to check that the values are sane to catch bugs like #27194

Fixes #23411, https://github.com/kubernetes/kubernetes/issues/31989

Fix package name bug

Fix https://github.com/kubernetes/client-go/issues/4#issuecomment-250061886

The copy.sh used to accidentally rewrite package name. This PR fixes that. It also picked up other changes in the code base to the staging area.

Make the restart test restart the nodes without a mig rolling update.

This is one approach to fix #33113. I switched from using a mig rolling-update to just pushing the reset button on the nodes and then waiting for their boot IDs to change.

Store RequestInfo in Context instead of RequestInfoResolver dependency injection

**Depends on https://github.com/kubernetes/kubernetes/pull/33478**

The `RequestInfoResolver` is used in the proxy handler and in the authorization code. It is passed through half of the apiserver code base to be available at those locations. This PR uses the context instead, which is our natural dependency injection mechanism in the handlers.

`RequestInfo` and all tooling around is moved to `pkg/apiserver/request` temporarily to avoid dependency cycles. This is necessary as long as `pkg/apiserver` implements the proxy and other handlers. Those might move to `pkg/apiserver/handlers` probably later.

Fix TestCreateWithNonExistentOwner

Fix #30228
As https://github.com/kubernetes/kubernetes/issues/30228#issuecomment-248779567 described, the GC did delete the garbage, it's the test logic failed. 
The test used to rely on `gc.QueuesDrained()`, which could return before the GC finished processing. It seems to be the only possible reason of the test failure. Hence, this PR changed the test to poll for the deletion of garbage.
