> A JournalManager may take hold of resources for the duration of their lifetime. This
isn't the case at the moment for FileJournalManager, but BookKeeperJournalManager will, and
it's conceivable that FileJournalManager could take a lock on a directory etc. 
> This JIRA is to add Closeable to JournalManager so that these resources can be cleaned
up when FSEditLog is closed.
