Bug 3161: Remove serialVersionUID to maintain backwards compatibility
The serialVersionUID field was added earlier in Lithium for
RaftActor.DeleteEntries and RaftActor.UpdateElectionTerm however it
breaks backwards compatibility. We need to remove serialVersionUID.
DeleteEntries has already been deprecated for a new class that has
serialVersionUID set and is not an inner class. I will do that same for
UpdateElectionTerm in another patch.
