  - TODO: review existing code in https://git.internal.justin.tv/release/deploy

Discussion:
  - deploying snapshots or branches?  Can a snapshot contain only a
    single branch?
    - everything is a snapshot
    - snapshot is created for each branch on the backend
  - what to do when branches are missing?
    - expose error
    - fail
  - Need to discuss cases like rebasing that will re-write the sha
