METRON-1695: Expose pcap properties through Ambari
## Contributor Comments
This change makes the PCAP config properties available via the Metron
service -> Configs tab in Ambari. It also takes care of updating the
`pcap.properties` file with relevant values depending on the deploy environment
(single node vs. multi node vs. kerberized cluster).
Here's a screenshot of the PCAP Config:
### Testing Steps
* Launch full dev
* Metron PCAP service should come up successfully.
* Go to Ambari -> Metron services -> Configs -> PCAP tab; change any config
parameter;
* Restart the required services and the config change take effect.
### Testing Done
I ran the following different tests to validate the fix.
#### A. Full Dev
* Verified Metron PCAP service comes up successfully
* Changed some of the PCAP config values from the Ambari UI, validated that
this is reflected in the `pcap.properties` file upon service restart.
- **Note**: I ran into
[METRON-1786](https://issues.apache.org/jira/browse/METRON-1786) during
testing. I was able to resolve the issue by applying the fix in PR #1206
#### B. Multi-node Cluster
* Validated that the `kafka.zk` property in `pcap.properties` is updated
with the correct Broker details
* Changed a PCAP service-related property (E.g. `kafka_pcap_numpackets`)
and validated that the `pcap.properties` file is updated.
* Changed a PCAP REST-related property (E.g. `pcap_page_size`) and
validated that the `/etc/default/metron` file is updated.
#### C. Kerberized Cluster
* Kerberized the multi-node cluster and setup pycapa
* Ingested PCAP into the cluster
* Ran queries through the PCAP panel and validated that the modified config
settings are in effect (E.g. `pcap_page_size` set to 50).
