Default NODE_OS to gci on GCE installs

Looking at https://github.com/kubernetes/test-infra/tree/master/jobs,
any job with "cvm" in the name explicitly sets this variable, so I hope
it is only the default.

**Release note**:
```release-note
Change GCE installs (kube-up.sh) to use GCI/COS for node OS, by default.
```

Use CollisionCount for collision avoidance in StatefulSet controller

**What this PR does / why we need it**:
This PR uses the newly added `CollisionCount` in `StatefulSetStatus` for name collision avoidance when the `StatefulSet` controller creates `ControllerRevision`s. The `CreateControllerRevision` method of the `ControllerHistory` interface was augmented to use a user-specified `collisionCount` instead of the internal probe that always starts with 0. The `StatefulSet` controller uses the `CreateControllerRevision` to create `ControllerRevision`s and when it calls it, it passes in the `CollisionCount` of the `StatefulSet` it manipulates.

Fix admission plugin registration

**What this PR does / why we need it**:
The current registration of admission plug-ins happen too late so the
command line help is not yielding correct/useful information to users.
This is already causing confusion as mentioned in some issues.

This patch fixes it by moving plugins.go down to options package because
"plugins" in this context are themselves options for users. Registration
of plugins is not an expensive operation and it is already done in most
execution paths.

**Which issue this PR fixes**
fixes #50833 

**Special notes for your reviewer**:
There might be other thoughts on how to better align this with other
efforts. This PR is leaving them to future work. For example:
in future, we may want to revisit these plugins and migrate them to the
shared apiserver repo when appropriate.

**Release note**:
I'm not sure if a release note is needed for this. Maybe there is a need.

AWS: Arbitrarily choose first (lexicographically) subnet in AZ

When there is more than one subnet for an AZ on AWS choose arbitrarily
chose the first one lexicographically for consistency.

If two subnets were to be used appear in the same aws az which one is chosen is currently not consistent.  This could lead to difficulty in diagnosing issues.

Make route-controller list only relevant routes instead of all of them

Ref https://github.com/kubernetes/kubernetes/issues/50854 (somewhat related issue)

IIUC from the code, route-controller memory is mainly being used in storing routes and nodes (also CIDRs, but that's not much).
This should help reduce that memory usage (particularly when running in a project with large no. of routes), by moving filtering to server-side.
For e.g in kubernetes-scale project we have ~5000 routes (each about 600B) => 3 MB of routes

This doesn't help with reducing time to list the routes as filtering is also linear.

NR Infrastructure agent example daemonset

Copy of previous newrelic example, then modified to use the new agent
"newrelic-infra" instead of "nrsysmond".

Also maps all of host node's root fs into /host in the container (ro,
but still exposes underlying node info into a container).

Updates to README



**What this PR does / why we need it**:  It provides an example basic configuration to get New Relic Infrastructure monitoring agent installed as a daemonset in containers on a cluster.  It started as a clone of examples/newrelic/, then updated to use the "infrastructure" docker image provided by New Relic.
