RaftAlgorithm	A simple little interface for receiving Raft RPC messages.
RaftBackedCache.ChangeListener<V>	This holds a locally registered callback that will be called whenever the cache changes.
RaftFailsafe	Failsafes are custom detectors that can make use of deploy-specific information (for example, spying on Kubernetes config) to cheat on CAP theorem limits about detecting cluster deadlocks.
RaftTransport	This encapsulates all the non-functional components in EloquentRaftMember so that the remaining code can be easily unit-tested.
Theseus.LongLivedLock	This holds a lock that is expected to live longer than the duration of a single method call.
