Change the config option from mds_id to mds_rank to reflect the fact that it's the rank we want to make use of (and will continue to want when we're doing stuff like force exporting from one rank to another). Fixes: #10361 Signed-off-by: Greg Farnum <gfarnum@redhat.com>

Run flush and scrub commands on the specified files in the filesystem. This

task will run through a sequence of operations, but it is not comprehensive

on its own -- it doesn't manipulate the mds cache state to test on both
|

in- and out-of-memory parts of the hierarchy. So it's designed to be run

multiple times within a single test run, so that the test can manipulate
