For tests to advertise that they need the client
to be able to trim its cache (i.e. currently that
means requiring run as root)

A means for test cases to mark particular methods
as long running, so that the vstart runner can skip
them when running for developers.
This is not a scientific thing, anything that takes
more than about 2 minutes due to lots of iteration
or sleeps.

In teuthology this isn't needed because we join the
mds child processes after killing them. In vstart
we're killing them asynchronously, so be a bit more
careful to ensure they can't re-insert themselves
to the mdsmap between our calling fail and our calling
fs rm.

Use this during test setup to check whether
a filesystem is configured at all, before
trying to tear it down.

To track recent change in master where instead of
crashing on missing MDSTable object we'll go
into damaged state.
Instead of catching a crash, handle the rank's
transition to the damanged state. Leave the crash
handling code (unused for the moment) in the
Filesystem class in case it's needed elsewhere
soon.

...to avoid having boilerplate in each test module,
and gain the ability to run them all in one go
with a nice test-by-test pass/fail report.

When unused clients were mounted during an fs new,
they would end up in a state where they stalled
on subsequent attempts to umount them (ceph-fuse
stalls on exit if it can't terminate its mds_session)

Now that we have more of these cases, there was lots
of duplication in setup and teardown. For some tests
the "reset everything" setup/teardown is overkill,
but it's harmless.

Some of this stuff could be even more general for embedding
unittest-style suites, but for the moment let's keep the cephfs
stuff in a walled garden.
