The snapshot branch seems to have more packages with fewer classes present in each. We should consolidate them down to a core set. I'm suggesting limiting it to:
o.a.h.h.errorhandling (move o.a.h.h.server.errorhandling.** to this package)
o.a.h.h.procedure (eliminate procedure.member, procedure.coordinator, possibly add zk for the zk implementation)
o.a.h.h.snapshot (move o.a.h.h.server.snapshots.** to this package)
o.a.h.h.master.snapshot (fold subpackages in)
o.a.h.h.regionserver.snapshot (fold subpackges in)
Likely move all TestSnapshotFrom* to o.a.h.h.snapshot.
