    Properly quote IPv6 address in RsyncDriver

    When IPv6 address literal is used as host in rsync call, it should be
    enclosed in square brackets. This is already done for copy_file method
    outside of driver in changeset Ia5f28673e79158d948980f2b3ce496c6a56882af

    Create helper function format_remote_path(host, path) and use where
    appropriate.
