Run the mon on each test on a different port so they can run in
parallel.

tests: remove vstart_wrapped_tests.sh

Listing tests to be run in a single script does not take advantage of
parallel runs in make.

The vstart_wrapper.sh script is reworked and made less specialized and
let the caller decide which daemons to run via CEPH_START and does not
enforce the number of deamons of each time. It no longer uses stop.sh to
avoid killing the osd/mon/mds that are unrelated to the tests.

tests: run workunits/cephtool/test.sh

Three scripts are added to run qa/workunits/cephtool/test.sh for each
daemon (mon, mds, osd) so they can be run in parallel.

tests: group workunits/cephtool/test.sh tests per daemon

So all tests related to a given daemon (mon, osd, mds) can be run at
once.

tests: kill_daemon use $name.pid instead of pidfile

So that it can be used instead of stop.sh to stop vstart.sh daemons. The
problem with stop.sh is that it kills any daemon, not just a selection.
