removes sync capability from operator

[ChrisJBurns]

Removes all sync code (automatic and manual) from the Operator. I tried to keep the manual sync but it was taking a bit too long to refactor and keep tests passing. For this reason, I've taken the entirety of the sync code. When we add multiple data sources, we have to rethink the sync code anyways and it makes sense to start from a fresh slate in this way. We can always ref to the old sync implementation if we need a reference/inspiration.

This PR is over 2k changes mainly because its removing of an entire capability. Trying to remove bits at a time resulted in more time due to fixing broken tests etc. It was easier to just remove them completely.
