This commit amends the MDS thrasher task to also work on multimds clusters. Main changes: o New FSStatus class in tasks/cephfs/filesystem.py which gets a snapshot of the fsmap (`ceph fs dump`). This allows consecutive operations on the same fsmap without repeated fs dumps. o Only one MDSThrasher is started for each file system. o The MDSThrasher operates on ranks instead of names (and groups of standbys following the initial active). o The MDSThrasher also will change the max_mds for the cluster to a new value [1, current) or (current, starting max_mds]. When reduced, randomly selected MDSs other than rank 0 will be deactivated to reach the new max_mds. The likelihood of changing max_mds in a given cycle of the MDSThrasher is set by the "thrash_max_mds" config. o The MDSThrasher prints out stats on completion, e.g. number of mds deactivated or mds_max changed.
