Metron 146 topology workers
This allows you to configure the number of workers in the enrichment
topology. The variable name is pretty long, for the sake of being verbose
(storm.topology.enrichment.workers, or in Ansible it is
storm_topology_enrichment_workers).
I tested this using the vagrant/quick-dev-platform image. After starting, I
ran the ./run_enrichment_role.sh script to start the enrichment topology. I
verified that the file has the configured value and the topology started
correctly. You can see in the ansible output that it tried to replaced the
variable here but the default value is the same since as the original value. I
can only run this on my laptop:
'''
TASK [metron_streaming : Configure Metron Solr topology]
***********************
<!--- SNIP -->
ok: [node1] => (item={u'regexp': u'storm.topology.enrichment.workers=',
u'line': u'storm.topology.enrichment.workers=1'})
'''
If someone could test changing the value on a real cluster that would be
great. I don't have the hardware for it.

flux...workers=int, not string; Also, ansible defaults undefined variable.
