Also: S3guard instrumentation has an interface and base implementation; metastores always have a non-null value; its used in the S3Guard API calls instead of delving into S3AInstrumentation internals. Note: just realised a problem here: only DDB metastore updates those counters. Never mind.

S3Guard Import to add a -auth command This will cause the meta store to marks the directory tree as authoritative once the import has completed its scan. It is off by default because you have to be 100% confident that during a potentially slow scan nobody is writing to that directory tree. This change includes moving the core operations of S3GuardTool.Import into an Importer class for ease of testing and so it can live alongside the auditor. They both use the same (new) MetadataStore method markAuthoritative(path, BulkOperation). For DDB, the AncestorState is used to determine what to mark -we don't attempt any listing of the directory tree. For Local S3Guard, is currently a no-op. I'm not worried about that, Especially as the auditor only audits DDB Tables. The documentation is yet to be updated!

When importing a listing and we find a file -we now query the store and only update the entry if the file is different from before, where different == new timestamp, etag, or length. Now, we can get timestamp differences due to clock skew in PUT operations: we can recognise this because the etags are the same. And, the recursive list operation doesn't retrieve the versionID, the existing entry may in fact be more complete. So in the special case of updating due to clock skew and Etag is the same, we copy over the version ID to the new entry. Looking at the S3Guard operations log in these test runs has shown that some of my "clever" optimisations over the summer where in fact "utterly wrong". Specifically, when adding an entry to the store, we PUT all the parent directory markers -without looking to see if they exist. As a result, any parent directory marked as auth is immediately marked as unauth if any file or directory is added anywhere underneath. Will fix in this (growing) PR.

Without this, our tests can leak FS and MS instances. We just hadn't noticed. The CLI entry point of S3GuardTool does the right thing and closes the tool; for our tests we have to explicitly do it. This is done in a mixture of try-with-resources and building up a list of tools to close in test tear down. All tests which patch in an existing metastore need to replace it with a null one before the close operation.

now non-verbose and verbose both print summaries of the operation: the number of files and dirs added. Note, well looking at the logging at debug level I can see that after the import, when we mark everything as authoritative, we end up overwriting all the dir entries just added. It's not that easy to avoid doing this while keeping the intermediate state of the S3Guard tables consistent; I'd have to modify that marking operation to do a Get on each dir and only update non-auth ones, while tagging the dirs as auth when created. It's doable; we'd be moving from two writes to one read, one write, or somehow blue together the tracking even more. I'm not convinced it's worth the extra complexity for an operation which is not expected to be run very often.
