METRON-1311 Service Check Should Check Elasticsearch Index Templates
The Service Check in Ambari does not validate that the Elasticsearch index
templates have been installed. Without these index templates bad things can
happen. For example, the Alerts UI will not be able to display any alerts.
With this PR, the Elasticsearch index templates that are installed by Ambari
are checked as part of the Metron Service Check.
## Testing
1. Launch a Metron environment like Full Dev
1. Run the Metron Service Check and ensure that it succeeds.
1. Click on Metron > Metron Indexing > Delete Elasticsearch Templates
1. Run the Metron Service Check and ensure that it fails with an error like
the following.
```
Missing Elasticsearch index template: name=yaf_index
```
1. Click on Metron > Metron Indexing > Install Elasticsearch Templates.
1. Run the Metron Service Check and ensure that it succeeds.
