This one is pretty serious... apparently AntiEntropyService is always
calculating who to initiate repairs with using getNaturalEndpoints(mytoken), so
when RF is less than the number of nodes, it is likely that trees are only sent
in one direction (clockwise around the ring). Additionally, we need to do the
inverse of getNaturalEndpoints, and determine which other nodes we are holding
replicas for.

> With Replicationfactor=2, if a server is brought down and its data directory
> wiped out, it doesn't restore its data replica after restart and nodeprobe
> repair.
> Steps to reproduce:
> 1) Bring up a cluster with three servers cs1,2,3, with their initial token
> set to 'foo3', 'foo6', and 'foo9', respectively. ReplicationFactor is set to
> 2 on all 3.
> 2) Insert 9 columns with keys from 'foo1' to 'foo9', and flush. Now I have
> foo1,2,3,7,8,9 on cs1, foo1,2,3,4,5,6, on cs2, and foo4,5,6,7,8,9
> on cs3. So far so good
> 3) Bring down cs3 and wipe out its data directory
> 4) Bring up cs3
> 5) run nodeprobe repair Keyspace1 on cs3, the flush
> At this point I expect to see cs3 getting its data back. But there's nothing
> in its data directory. I also tried getting all columns with
> ConsistencyLevel::ALL to see if that'll do a read pair. But still cs3's data
> directory is empty.
