> This JIRA is for some simple refactors in the NN:
> - refactor the code which writes the seen_txid file in NNStorage into a new
> "LongContainingFile" utility class. This is useful for the JournalNode to
> atomically/durably record its last promised epoch
> - refactor the interface from FileJournalManager back to StorageDirectory to
> use a StorageErrorReport interface. This allows FileJournalManager to be used
> in isolation of a full StorageDirectory.
