Avoid indexing the same workspace multiple times (#15495)
## Summary

This is not lazy indexing but it should somewhat help with #13686.

Currently, processing the change notifications for config files doesn't
account for the fact that multiple config files could belong to the same
workspace. This means that the server will re-index the same workspace
`n` times where `n` is the number of file events which belongs to the
same workspace. This is evident in the following trace logs:

**Trace logs:**

This PR updates the logic to consider all the change events at once
keeping track of the workspace path that have been already indexed.

I want to include this in tomorrow's release to check how this change
would affect the linked issue.

## Test Plan

Run the same scenario as above and check the logs to see that the server
isn't re-indexing the same workspace multiple times:
