Description ewolinet 2021-02-01 22:28:15 UTC

+++ This bug was initially created as a clone of Bug #1920215 +++

Description of problem:
Index Templates are high priority items in the Elasticsearch cluster, and constantly updating them (even when nothing has changed) can cause the cluster to deprioritize what it is currently doing to ensure that the templates are replicated across the cluster.

Version-Release number of selected component (if applicable):
4.6.z

How reproducible:
Always

Steps to Reproduce:
1. Deploy EO
2. Create es CR with index management section (required)
3. Observe in the logs ES creating/updating the ocp-gen-* index templates constantly

Actual results:
Index Templates are always updated

Expected results:
Templates are only updated when a change is necessary
