Convenient when you want to create a fresh cluster
each test run: just pass --create and you'll get
a cluster with the right number of daemons for
the tests you're running.

Previously this could get hung up if we killed one
PID and then the daemon reappears with a different
one (perhaps because we caught it during
daemonization?)

If we checkout ceph-ci.git, and don't find a branch,
we'll try again from ceph.git. But the checkout will
already exist and the clone will fail, so we'll still
fail to find the branch.
The same can happen if a previous workunit task already
checked out the repo.
Fix by removing the repo before checkout (the first and
second times). Note that this may break if there are
multiple workunit tasks running in parallel on the same
role. That is already racy, so if it's happening, we'll
want to switch to using a truly unique clonedir for each
instantiation.

...before sending a tell command. Otherwise osd.2 might
start without 1, the io unblocks, and the tell fails
because osd.1 is still down.
