METRON-1283: Install Elasticsearch template as a part of the mpack startup scripts ## Contributor Comments For a Metron multi-node deployment using mpack, the Elasticsearch template is required to be installed manually post-setup. These templates are required for the proper working of, for e.g. the Alerts UI. In the event that these templates are not installed, and if data is ingested, these would not be shown in the Alerts UI, since there would be missing fields without the template files (E.g. snort alert indices are not displayed in the Alerts UI, since it is missing the "alerts" field from the mapping). In such a case, one needs to install the templates, delete all indices for the given parser and re-ingest data again into the parser for it to appear in the Alerts UI. Further, the indices from all the parsers will have to be deleted and re-ingested again which could be a tedious job in the event that this step was missed out by chance. I have also seen other ill-effects from having stale indices for parsers that was created before template install. While documenting the template installation is a good practice, nothing would more failsafe than installing the template as a part of the mpack startup scripts itself. I have added the ES template install step just before starting the Indexing topology, since I found this to be the closest related step when this could be done. Do let me know if this needs to be moved to a different point in the startup, and I can make the change. **Testing Done** * Built mpack with the changes * Deployed a 12-node Metron setup using the mpack * Validated that the start Indexing topology step also installs the Elasticsearch template files. ## Pull Request Checklist Thank you for submitting a contribution to Apache Metron.
