    Remove percona repo if not used

    If the ``use_percona_upstream`` value is changed from True to False,
    don't remove the existing repository. This is also the source of a bug
    in Mitaka: We were installing the repo by default and installed the
    percona-xtrabackup tool with a deb file. If another playbook/role
    installed percona-xtrabackup, it would override (and probably upgrade)
    the deb installed version, which is undesired.
