Just a comment on the description of the JIRA, not the code change itself.
Index templates can only be installed when starting the Indexing topology, not
during install. During install, Elasticsearch is most likely not running yet.
That being said, I think the ask here is that starting the indexing topology
should fail, if the index templates fail to install. And this is what you have
with your PR.---
