 Description   

The MovePrimarySourceManager will be analogous to the MigrationSourceManager: it will be the "state machine" for movePrimary.

However, unlike the MigrationSourceManager, it will not need to have a MigrationChunkClonerSource analog, since it will not need any of the MigrationChunkClonerSource's

Instead, it will just have a state (for debugging) and a set of functions it will progress through.

It should be a Decoration on DatabaseShardingState for easier debugging from a core dump.
