autoconf: discover volume list and info separately
NRPE doesn't support transfering large junk of data as a result. Hence we have to discover the volume details one by one. First fetch the volume list using 'discover_volume_list' NRPE command then fetch the brick details of volume one by one using 'discover_volume_info' NRPE command Change-Id: I2cd3c2309ffa2f1bf5c271e06dd03ade75bf5d92 Signed-off-by: Ramesh Nachimuthu <rnachimu@redhat.com> Reviewed-on: http://review.gluster.org/7631 Reviewed-by: Sahina Bose <sabose@redhat.com>
