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
