    @anandsubbu Thanks for contributing this!  The only thing I'm unsure of 
after reviewing this is your comment regarding this belonging in 
parser_master.py or not. On one hand, you could make a case that this is a 
parser like any other with the exception that it is spout-only. On the other 
hand, we don't currently provide a mechanism (iirc) to start/stop/manage the 
PCAP topology from Ambari. Starting parsers doesn't start PCAP, does it? 
    
    It may be that PCAP deserves its own "master", e.g. pcap_master.py, and 
lifecycle as a proper first class citizen (topology) within Ambari. Below is 
the current list of components, and PCAP is not in it afaik, even as a parser 
(there's a start_pcap_topology.sh script that is NOT the same as 
start_parser_topology.sh). It seems like if we're going to add this to Ambari 
we should also provide the ability to manage it. What do you think of that 
approach?

> Currently, the $METRON_HOME/config/pcap.properties file is hardcoded with the 
> defaults. One has to hand edit the file before deploying the PCAP topology. 
> These properties should be configurable via Ambari.
