Ops move: Enable Gitaly and add itself as an external server
What
Enables in-cluster Gitaly on the new us-central1
Ops cluster, and adds an entry to the Gitaly server list that points to itself (this will be used to complete the migration).
Why
Currently we are transparently using the Gitaly node on the VM via the cluster, but we will need the cluster to have its own node to be able to do the migration.
