Much like ~~SERVER-24933~~, we should ensure that our shutdown lands between apply batches.

There are a few ways to get there:

Ignore shutdown interruptions during apply batch (not good for long running applies like index builds)
Have shutdown wait for the current apply batch (similar to above)
Undo/reset current batch work on shutdown to be in a consistent state

In addition we should move setting the minvalid boundaries under the PBWM lock so that minvalid reflects the completed apply batch.
