Fix master regex when running multiple clusters
**What this PR does / why we need it**:
I'm running two Kubernetes clusters on GCE. One for production and one for staging. The instance prefix I use for production is `kubernetes` and for staging it's `staging-kubernetes`. This caused a problem when running `kube-up.sh` for production because when it tries to find all instances which match `kubernetes(-...)?` it finds both the production and staging instances. This probably results in multiple problems, but the most noticeable one for me was that `INITIAL_ETCD_CLUSTER` was incorrect and so etcd wouldn't start up correctly so the api server doesn't start up correctly so nothing else starts up. I tested this manually and it seems to work for me, but I didn't write an automated test.

basically just:
* move all manifests into the new gce/manifests dir
* move limit-range into gce/addons/limit-range
* move abac jsonl into gce/manifests. this is gross but we will
hopefully be able to delete this config soon. it only exists to support
a deprecated feature.
* fix build, release, deploy to look for everything in its new home

Updated Flexvolume setup mechanisms for COS instance image.
- If REMOUNT_VOLUME_PLUGIN_DIR is set to true, VOLUME_PLUGIN_DIR is remounted with `exec` option during cluster startup. This allows any writable location to be used as the plugin directory.
- New HostPath added to controller-manager deployment to enable access to volume plugin directory.
- Improved how the default directory is passed to master and node setup.

We shouldn't upgrade etcd without first warning the user that some etcd
version transitions can't be undone. We don't know what version the user
currently has, so we require either an explicit version and image, or an
interactive acknowledgement of this caveat.
This is modeled after the STORAGE_MEDIA_TYPE prompt just above.
