Automatically add GitHub mirrors

This CL adds a check to validate that the GitHub mirror repo exists
before syncing. If the mirror remote is missing it is created using the
GitHub developer API (https://developer.github.com/v3/repos/#create).

NOTE: This CL assumes authentication is handled via a ~/.netrc file
with entires for:

    machine api.github.com
      login <username>
      password <token>

    machine github.com
      login <username>
      password <token>

The `<token>` value above being generated by: https://git.io/vmNUX
