Fixes all updates since bcwaldon sketched the original, with cleanup and into an acutal working state. The commit log follows: fix pb reference and remove unused file post rebase unbreak the migrate folder correctly detect node IDs fix snapshotting Fix previous broken snapshot Add raft log entries to the translation; fix test for all timezones. (Still in progress, but passing) Fix etcd:join and etcd:remove print more data when dumping the log Cleanup based on yichengq's comments more comments Fix the commited index based on the snapshot, if one exists detect nodeIDs from snapshot add initial tool documentation and match the semantics in the build script and main formalize migration doc rename function and clarify docs fix nil pointer fix the record conversion test add migration to test suite and fix govet
