Scenarios:
(1) A and B and C all in VOTING, adding D, quorum of size 2:
D goes into RECOVERING, recovers then goes into VOTING.
(2) A and B in VOTING, adding D, quorum size of 2:
D goes into RECOVERING, recovers then goes into VOTING.
(3) A in VOTING, adding D, quorum size of 2:
D tries to recover forever.
(4) A in VOTING and B in EMPTY, adding D, quorum of size 2:
D tries to recover forever.
(5) A in VOTING and B in STARTING, adding D, quorum of size 2:
D goes into VOTING, does not recover from A, B does the same thing.
(6) A in VOTING and adding B which was initailized with STARTING, quorum of size 2:
B goes into VOTING, does not recover from A.
