Script to cache metadata requests on the jenkins master

Fixes https://github.com/kubernetes/kubernetes/issues/23545

Create an http server which caches most requests to the metadata server. Use special logic to cache access tokens such that the expires_on json field is correct. Add a script to simplify enabling/disabling the cache by editing `/etc/hosts`

Collect and expose runtime's image storage usage via Kubelet's /stats/summary endpoint

This information is useful to users since docker images are typically not stored on the root filesystem.

Kubelet will also consume this feature in the future to decide is evicting images will help with disk usage on the nodes.

Move internal types of job from pkg/apis/extensions to pkg/apis/batch

This addressed the job part of #23216, this is still WIP. Will notify once finished. I'd like to have it in before starting working on ScheduledJob.

Use kube-system namespace

Fixes #23153.

Sadly, kube-system isn't automatically created, so people need to make
sure to create it in their turnup scripts.  Also after creating
kube-system it can take 10+ seconds for master and proxy to show up.

I tested the equivalent of these changes locally, but not these changes
themselves as I don't have a dev/build env up, so please read carefully
and maybe try them out!

use single writer to improve quota performance

Performance improvement is comparable to https://github.com/openshift/origin/pull/6658, though I'm getting some crazy stalls during initial calculation on master (not on this branch), so there may be an existing problem.  This implementation won't scale out quite as well, but I don't think we'll need much more for a while and this one is easier to read.

This buckets based on namespace, then bunches updates where possible to avoid request fanout, and does fast notification when it can.  It correctly handles updating multiple quota docs.

Make detect-node-names less brittle for G{C,K}E

Use the `--format='value()'` option with `gcloud compute instance-groups managed list{,-instances}` instead of `--format=yaml` with a series of `grep`s and `cut`s. This is hopefully a bit more stable.

Fixes #24120.
