On SERVER-131169, we temporarily disabled the ContinuousAddRemoveShard hook on DSC because SERVER-129673 caused timeout failures.

Those timeouts were triggered by the combination of DSC's unusually large snapshot window (about 1800 seconds) and the change introduced in SERVER-129673, which can cause moveChunk to be rejected until that snapshot window has elapsed.

To reduce the impact of SERVER-129673 on tests, we introduced a new test-only server parameter that controls how long moveChunk should wait before proceeding when the recipient range is still accessible to point-in-time reads. This work is tracked in SERVER-132078.

With that change, we can now re-enable those tests that we disabled in SERVER-131169.
