Leverages the JMeter and KafkaMeter to inject into persister metric
messages with permutation of random metric names and dimensions.
Monitors the metrics flushed to the database in all persister
instances and calculates the throughput. The number of metrics and
the number of unique metic definitions are configurable in the test
plan. The script currently supports only the Java implementation of
the Monasca persister. Monasca python does not provide the same
internal metric api as the Dropwizard in the Java implemation.
Future work is required for the Python implemation.
