METRON-1798: Add mpack support for parser aggregation ## Contributor Comments This pull request allows users to submit an aggregated parser topology. ## Testing Steps 1. Spin up full-dev. 2. Stop the "Metron Parsers" service so that existing parser topologies are killed/stopped. 3. Go to Ambari -> Metron -> Configs -> Parsers 4. Change the "Metron Parsers" value as: "bro,snort", "yaf (For example) 5. Save changes and restart the Metron Parsers service. 6. Go to Storm UI, and verify that the aggregated topologies viz. "bro__snort" and "yaf" are started. ## Testing Done ### 1. Full Dev * Set the Metron Parsers value as "bro,snort.yaf" and restarted the service. * A single aggregated topology is seen to be started: ![image](https://user-images.githubusercontent.com/20395490/46216724-dbb13a00-c35d-11e8-9651-b39d0766208f.png) * Verified stop 'Metron Parsers' service to check that the aggregated topology is stopped properly * Verified restart 'Metron Parsers' service to check that the aggregated topology is restarted properly ### 2. Multi-node setup * Set the Metron Parsers value as: "bro,snort,yaf","bro,yaf","snort,yaf",yaf,snort * The appropriate aggregated and single topologies are started: ![image](https://user-images.githubusercontent.com/20395490/46217047-84f83000-c35e-11e8-87e3-994b72d06cf3.png) ## Pull Request Checklist Thank you for submitting a contribution to Apache Metron.
