Deprecate class FakeThreadPoolMasterService, BlockMasterServiceOnMaster and BusyMasterServiceDisruption, in 'test/framework' directory

[tlfeng]

Description

To support inclusive language, the master terminology is going to be replaced by cluster manager in the code base.

In a previous PR #4051 / commit bea5d1a, 3 classes in test/framework directory that contains master in the name were renamed:

FakeThreadPoolMasterService -> FakeThreadPoolClusterManagerService
BlockMasterServiceOnMaster -> BlockClusterManagerServiceOnClusterManager
BusyMasterServiceDisruption -> BusyClusterManagerServiceDisruption

This is a following PR to add back the classes with the old name to keep the backwards compatibility. The classes with the old name will be subclass of the classes with new name, so that maintaining one implementation can support the usage for two classes.
