func InspectFilesystem(fsOpts Options) (Inspection, error)
InspectFilesystem scans the filesystem and generates a Inspection which the commitlog bootstrapper needs to avoid reading commitlog files that were written *after* the process has already started. I.E in order to distinguish between files that were already on disk before the process started, and those that were written by the process itself once it started accepting writes (but before bootstrapping had complete) we export a function which can be called during node startup.
