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.
