Support deploying Monasca Thresh

Monasca Thresh is a Storm topology which generates alerts from
metric streams according to alarms defined via the Monasca API.

This change runs the thresholder in local mode, which means that
the log output for the topology is directed to stdout and the
topology is restarted if the container is restarted. A future
change will improve the log collection and introduce a better
way of the checking the topology is running for multi-node
clusters.
