    Make bootstrap idempotent when it needs to be

    This commit makes `keystone-manage bootstrap` completely idempotent
    when configuration values or environment variables haven't changed
    between runs. If they have changed, then `bootstrap` shouldn't be
    as idempotent becuase it's changing the state of the deployment.

    This commit addresses these issues and adds tests to ensure the
    proper behavior is tested.
