METRON-1499 Enable Configuration of Unified Enrichment Topology via Ambari
We recently introduced an alternative enrichment topology; the Unified
enrichment topology. This is an alternative to the existing Split Join
topology. This work enhances the MPack so that a user can configure, stop, and
start either the Unified or the Split Join enrichment topology.
* Each topology has a separate configuration section under the Metron >
Enrichment settings in Ambari.
* A combo box allows the user to choose which Enrichment topology should be
run.
* The Split Join topology remains the default Enrichment topology.
* The `bin/start_enrichment_topology.sh` script was enhanced so that you
can pass in the `--filter` and `--remote` args directly to launch an
alternative topology. Running the script with no parameters will launch the
default topology; Split Join.
* The Unified topology had previously reused some of the same settings from
the Split Join topology. Where it made sense, the Unified topology was updated
to use its own logically named properties.
* There are now separate properties file for each Enrichment topology.
`$METRON_HOME/config/enrichment-splitjoin.properties`
`$METRON_HOME/config/enrichment-unified.properties`
* There are separate flux files for each Enrichment topology.
`$METRON_HOME/flux/enrichment/remote-splitjoin.yaml`
`$METRON_HOME/flux/enrichment/remote-unified.yaml`
### Manual Testing
To test this change, launch a development environment. The Split Join
Enrichment topology will be running by default. Switch to the Unified
topology. Change some settings and make sure they are reflected in the
topology.
