GitLab

Description:
Creating just a Gerrit password isn't enough.  Before you can push a
change to Gerrit, you must also create/associate a Gerrit account with
the google account used to create the password.

This avoids "git push ..." rejections like this:

  remote: PERMISSION_DENIED: The caller does not have permission
  remote: [type.googleapis.com/google.rpc.LocalizedMessage]
  remote: locale: "en-US"
  remote: message: "\'git push\' requires a Gerrit user account."
