Delete old files

[ovv]

Slack as set a usage limit on the number of files for slack teams. We should monitor that and delete the old ones that are inactive so we don't get a warning when uploading new files

I don't see anywhere in the API to mine slack for "unused" or "last seen/downloaded" files that might be used to define "inactive".

@dangarthwaite I think you probably need a combination of files.list and files.info. The latter has a "created" key that should give a pretty good indication, since we go through the history limit in 4-6 days usually. Anything older than a week is definitely a removal candidate.

Actually the files.list has a parameter ts_to, so you could just ask for all files before now - 1 week, and delete them (maybe only allowing that for files in public channels).
