Title: Add ability to return a single tag to the pool of available tags.

Sometimes, for whatever reason (like a bug) a tag isn't returned to the pool of the available tags when it was meant to be closed.

When that happens currently our only means of recovery is fiddling with commands in production redis. I'd prefer a command line tool that does that for us.
