Issue Summary

On every Jira restart, Insight indexing(freetext-reindex) is triggered (i.e., irrespective of nodes).

Though we have options to "Persist Insight index to file" & increasing the "Tomcat shutdown time" which is not useful to not have auto re-index during restart.

As a result - Insight will always re-index on restart.

Jira administrator should have control to disable auto re-indexing of Insight.

Steps to Reproduce

1. Restart Jira.

Expected Results

1. Once the application is started, Insight should not re-index automatically.

Actual Results

1. Once the application is started, you'll see that the Insight re-indexing is started.
