[Meta] Unattended promises that might require retries

[afharo]

When addressing #181456, we identified many unattended promises that install/create objects (indices, templates, tasks, SOs) during Kibana startup phase. Before fixing unhandledRejections, a failure in any of these would mean Kibana crashing and being restarted by the orchestration architecture (which meant an automatic retry)

Now that we catch the promises, promises might fail and still not crash Kibana, meaning the objects won't be created and result in unexpected behavior.

This is a meta issue to collect all the individual cases we've identified in that PR:
