TransactionMetadataCache is split into transaction specific cache and log header cache, which follows better the way it is used. PhysicalLogFile needs a LogHeaderCache and a last committed id provider, which removes all dependence on transaction concepts. This is in preparation for using PhysicalLogFile to implement a new version of the RaftLog.
