Add support for deploying Monasca Thresh

Monasca Thresh is a Java topology for Storm which generates
alerts from metrics. It depends on Java code in the
monasca-common library. In this change we support building
the Monasca Thresh Storm topology from source. To enable us
to submit the topology to Storm we inherit from the Storm
container (rather than the Monasca base image) so that we can
use the Storm client.
