Implement a filesystem watch to enable automated ingestion

[lewismc]

At a previous meeting with ICCAT it became obvious that data entry in the swaggerui was resulting in botched ingestion tasks. The issue stemmed from copy-paste of things like file paths/locations.

Files could be rsync'd onto the Rackspace machine and automatically ingested via some fswatch-like capability which would watch for changes in file system and invoked POST.
