GPFS manila share service fails while performing certain operations as 'root'

[Nilesh Bhosale]

With a recent change (https://review.openstack.org/#/c/144859), while merging "volume" and "share" rootwrap filters into one file, some of the filters from volume.filters were removed considering those to be unused. But, GPFS manila driver uses those and fails while performing certain operations, in their absence.
Like the below one:

    Adding required rootwrap filters for GPFS driver

    The rootwrap filters for commands 'df' and 'stat', which were part
    of the volume.filters before, were recently removed considering those
    to be unused. But, GPFS manila driver uses those and fails while
    performing certain operations, in their absence.
    Hence, adding those back.
