refresh_monasca_script.sh is useful for
development in a devstack environment.
Enhanced the script to
* start and stop monasca-transform process
running in a screen session
* added more hardening to catch for errors
and exit if any command fails.
* added debugging statements help track
down any errors when the script is run.

The monasca-transform is a new component in Monasca that
aggregates and transforms metrics.
monasca-transform is a Spark based data driven aggregation
engine which collects, groups and aggregates existing individual
Monasca metrics according to business requirements and publishes
new transformed (derived) metrics to the Monasca Kafka queue.
Since the new transformed metrics are published as any other
metric in Monasca, alarms can be set and triggered on the
transformed metric, just like any other metric.
