Pass in etcd TLS credentials during migrate and rollback
For HA etcd clusters, the `etcd-creds` settings, specifically the `--peer-*` TLS flags that may be included, must be passed in to `start-stop-etcd.sh` in order for the etcd server mode started during migrate and rollback steps to be able to communicate between peers.
The `etcd.manifest` change needs to be backported all the way back to 1.7.
**Release note**:

This is the 2nd attempt. The previous was reverted while we figured out
the regional mirrors (oops).
New plan: k8s.gcr.io is a read-only facade that auto-detects your source
region (us, eu, or asia for now) and pulls from the closest. To publish
an image, push k8s-staging.gcr.io and it will be synced to the regionals
automatically (similar to today). For now the staging is an alias to
gcr.io/google_containers (the legacy URL).
When we move off of google-owned projects (working on it), then we just
do a one-time sync, and change the google-internal config, and nobody
outside should notice.
We can, in parallel, change the auto-sync into a manual sync - send a PR
to "promote" something from staging, and a bot activates it. Nice and
visible, easy to keep track of.
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
