As of I7353af4c3f141d4bd617d6fd388d7957e0586ba8 we'll introduce
the ability to have a 2 layer config which includes the messages
that we'll send back to the user on gerrit outside of the
elastic-recheck code base. This makes it easier to make changes
to the UX consistent with what we want to change with the rest
of the config.
