and '(remote,) = ctx.cluster.only(role).remotes.iterkeys()' would fail with
ValueError and no message if there were less than 0 or more than 1 key.
Now a new function, get_single_remote_value() is called which prints out
more understandable messages.

The exitstatus on the process is a gevent.AsyncResult
(not an int). Use the try/except pattern for handling
errors instead.

The last command a restart script outputs is 'done'
indicating the script does not require being restarted
further. Handle this case properly.

The ceph daemons support being killed at a specific code point
with a config option. In some cases, we want to test a kill point
only once for a given daemon run (such as replay that only occurs
during daemon startup). This task allows running a script or executable
and (when the script sends a command to the task) restarting it with
a temporary config that has the appropriate kill point set. Once
the daemon asserts and gets restarted, the original config is used.
Adds a specific restart_with_args() method to the DaemonState in the
ceph task.
Right now this task follows the workunit task closely, but uses stdout/stdin
to specify when to restart a daemon.
