After MongoDB 3.6 is released, all oplogs will be required to have a UUID entry, making the no_uuid rollback files unnecessary. rs_rollback_no_uuid.cpp/.h and rs_rollback_no_uuid_test.cpp should all be removed at this point. Additional code that allowed for the old rollback algorithms to work should also be deleted. The failpoint declarations
should be moved out of roll_back_local_operations.cpp/.h and moved into rs_rollback.cpp after rs_rollback_no_uuid.cpp/.h are deleted. The Sconscript will need to be adjusted accordingly as well.
