The duration is impresise and sometimes will give a false alarm
just in case the shell command itself is issued late.

Add method get_ceph_cmd_stdout() to class CephFSTestCase so that one
doesn't have to type something as long as
"self.mds_cluster.mon_manager.raw_cluster_cmd()" to execute a
command and get its output. And delete and replace
CephFSTestCase.run_cluster_cmd() too.

This is one test case for the possible kernel crash bug when doing
the file sync or filesystem sync.

This will test the file sync of a directory, which maybe stuck for
at most 5 seconds. This was because the related code will wait for
all the unsafe requests to get safe reply from MDSes, but the MDSes
just think that it's unnecessary to flush the mdlog immediately
after early reply, and the mdlog will be flushed every 5 seconds
in the tick thread.
This should have been fixed in kclient and libcephfs by triggering
mdlog flush before waiting requests' safe reply.

Setting the pg_num to 8 is too small that some osds maybe not covered by the
pools, some osds maybe overloaded. Remove the hardcodeing pg_num here and let
the pg autoscale mode to calculate it as needed, and at the same time set the
pg_num_min to 64 to avoid the pg_num to small.
If ec pool is used, for the test cases most datas will go to the ec pool and
the primary replicated pool will store a small amount of metadata for all the
files only, so set the target size ratio to 0.05 should be enough.

It's not yet possible to completely remove the dependency on
mds_ids/mds_daemons in the CephFS tests but this commit reduces it
enough for most code paths to work with cephadm.
The main change here is use of CephManager.do_rados, with some
improvements.

Instead of stopping MDS daemons and individually failing MDS daemons,
just fail the ranks or the entire file system, where possible.

Using self.fs.mon_manager in mount.py can lead to a crash since self.fs
can be None. Move is_blocklisted() to tasks.filesystem.CephCluster where
it can get access to mon_manager without depending on objects
representing Ceph FSs.

Mostly we should wait the mountpoint to get ready, especially for
the fuse mountpoint, sometimes it may take a few seconds to get
ready.

There were a couple of problems found by flake8 in the qa/
directory (most of them fixed now). Enabling flake8 during the usual
check runs hopefully avoids adding new issues in the future.

The pg count needs to be a power-of-two since
dff5697464.
Also, mon_pg_warn_min_per_osd is disabled by default now (or set to a
low value in vstart/testing) so there's no need to base the pg count on
this value.
Ideally someday we can remove this so that the default cluster value is
used but we need to keep this for deployments of older versions of Ceph.

`cache drop` is a long running command that will block the asok interface
(while the tell version does not). Attempting to abort the command with ^C or
equivalents will simply cause the `ceph` command to exit but won't stop the
asok command handler from waiting for the cache drop operation to complete.
Instead, just allow the tell version.
