rename StoreToControllerLister -> StoreToReplicationControllerLister to make room for more controllers

Currently setting the `--allocate-node-cidrs` flag to true with an
empty cloud provider causes the kube-controller-manager to crash during
startup.

Fix the issue by checking for an empty cloud provider before setting
up route management on the cloud provider. This change introduces a
change in behavior. The kube-controller-manager now supports allocating
pod CIDRs without a cloud provider. This means users must manage routes
through some other mechanism.

The controller manager logs a warning if `--allocate-node-cidrs` is set,
but not a cloud provider:

```

Fixes #11866

Refactor git repo volume to separate builder and cleaner

kube-apiserver.service has 'ExecStartPre=/usr/bin/mkdir -p /var/lib/kube-apiserver', but if server is not fast enough 'mv /home/core/known_tokens.csv /var/lib/kube-apiserver/known_tokens.csv' will fail.

Use example syncer tags instead of hard-coded examples in doc

This should ensure all load balancers get deleted even if a reordering of
watch events causes us to strand one after its service has been deleted,
because the sync will notice that the service controller's cache has a
service in it that no longer exists in the apiserver.

It could still leak in the case that the controller manager is killed
between when it leaks something and the sync runs, but this should
improve things.
