Add Monasca Agent container

The Monasca Agent consists of 3 processes. The collector, which
collects system level metrics from a host, a statsd server, which is used
to receive application specific statsd metrics and a forwarder service
which batches metrics and sends them to the Monasca API at pre-defined
time intervals.
