In this PR, the blob manager now recruits blob workers
(via communication with the cluster controller). Blob workers
are onboarded as blob worker processes enter the cluster.

Refactor logic for recruiting singletons.
...
This commit refactors the logic for recruiting singletons,
which is done by the ClusterController. This allows for far
easier additions of new singletons in the future, and also
cleans up the code.
Also, the logic for recruiting DD was changed to mirror
the logic for recruiting RK. Although the logic for RK
allows there to be many RKs existing at once, the moveKeysLock
mechanism used by DD still prevents multiple DDs existing at once.
