move core storage out of master.go
Moves the core resource creation out of master.go and makes it more congruent to the other storages.
WIP because I haven't run tests yet, but I figured I'd see what breaks in the morning.

Allow anonymous API server access, decorate authenticated users with system:authenticated group
When writing authorization policy, it is often necessary to allow certain actions to any authenticated user. For example, creating a service or configmap, and granting read access to all users
It is also frequently necessary to allow actions to any unauthenticated user. For example, fetching discovery APIs might be part of an authentication process, and therefore need to be able to be read without access to authentication credentials.
This PR:
* Adds an option to allow anonymous requests to the secured API port. If enabled, requests to the secure port that are not rejected by other configured authentication methods are treated as anonymous requests, and given a username of `system:anonymous` and a group of `system:unauthenticated`. Note: this should only be used with an `--authorization-mode` other than `AlwaysAllow`
* Decorates user.Info returned from configured authenticators with the group `system:authenticated`.
This is related to defining a default set of roles and bindings for RBAC (https://github.com/kubernetes/features/issues/2). The bootstrap policy should allow all users (anonymous or authenticated) to request the discovery APIs.
```release-note
kube-apiserver learned the '--anonymous-auth' flag, which defaults to true. When enabled, requests to the secure port that are not rejected by other configured authentication methods are treated as anonymous requests, and given a username of 'system:anonymous' and a group of 'system:unauthenticated'.
Authenticated users are decorated with a 'system:authenticated' group.
NOTE: anonymous access is enabled by default. If you rely on authentication alone to authorize access, change to use an authorization mode other than AlwaysAllow, or or set '--anonymous-auth=false'.

Support Access-Control-Expose-Headers in CORS Handler
Our typical HTTP Response has a "Date" Header, if we don't add an
additional http header "Access-Control-Expose-Headers: Date" then
the browser based clients cannot use the Date HTTP Header.

add linebreak between resource groups
**Release note**:
```release-note
release-note-none
```
Printing multiple groups via `kubectl get all` can produce output that is
hard to read in cases where there are a lot of resource types to display
/ some resource types contain varying column amounts.
This patch adds a linebreak above each group of resources only when
there is more than one group to display, and always omitting the
linebreak above the first group. This makes for slightly improved
output.
Linebreaks are printed to stderr, and honor the `--no-headers` option.

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.

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.
Printing multiple groups via `kubectl get all` can produce output that is
hard to read in cases where there are a lot of resource types to display
/ some resource types contain varying column amounts.
This patch adds a linebreak above each group of resources only when
there is more than one group to display, and always omitting the
linebreak above the first group. This makes for slightly improved

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.
