Description of problem:
We should have a foreman rake or other mechanism to remove old and un-needed packages from Satellite. While this can be accomplished fairly easily on Capsules, there is no easy way to do this on Satellite.
Even with on-demand downloading, a Satellite that has been upgraded several times will have an enormous amount of space used by packages that are no longer used. Removing a repo and re-adding it to Satellite is virtually impossible. There are tons of packages that are not being deployed anymore that could easily be removed to free up space.
Having a mechanism to remove packages that haven't been used in 30, 60, or 90 days would greatly reduce space needed. Then, if for some reason that package is needed again, the on-demand nature of the Satellite should allow the package to be re-downloaded from the CDN.
