METRON-1834: Migrate Elasticsearch from TransportClient to new Java REST API
## Contributor Comments
https://issues.apache.org/jira/browse/METRON-1834
This task has been a long time coming after having completed the ES upgrade
in https://issues.apache.org/jira/browse/METRON-939. Motivation for completing
this now is that Elasticsearch will be deprecating use of the TransportClient
in v 7.x. This PR migrates the Elasticsearch client from TransportClient to the
newer Java REST API.
1.

3.
https://www.elastic.co/guide/en/elasticsearch/client/java-rest/5.6/java-rest-high-level-migration.html
This builds off and finishes work started by @cestella here -
https://github.com/cestella/incubator-metron/tree/es_rest_client. I condensed
his branch into 1 flattened commit and built on top of it in order to provide
attribution.
I have a number of tasks I'm still working through, but I wanted to get the
review process started. I've minimally validated X-Pack auth and will have some
follow-up for SSL. Test plans and a breakdown of the changes will be soon to
follow. For starters, full dev should continue to work as normal and you should
see data flowing into indexes for bro, snort, and yaf. There are some
additional changes to how this client will be configured, which I'll be
documenting shortly. The new client does not take a Map of settings any longer
now that it is leverage Apache HTTP Async Client
https://www.elastic.co/guide/en/elasticsearch/client/java-rest/5.6/java-rest-low-usage-dependencies.html
under the hood. This meant choosing a set of properties to expose and doing a
translation to the builder pattern under the hood. Again, I'll have a write-up
of this in the migration guide and update the README's accordingly.
NOTE: This checks off 2 items from this follow-on list
https://github.com/apache/metron/pull/840#issuecomment-347281776
1. Fix Log4j logging problem - classpath issues
2. Migrate to new ES REST client
Per discussion in the Metron Slack channel, I will be updating the Jira
ticket with a series of tasks to be completed prior to acceptance, including
performance regression testing compared with the old API.
