gitserver deletes all repositories if the disk size is ~= SRC_REPOS_DESIRED_FREE_GB
Created by: ggilmore
Gitserver periodically runs a cleanup job so that it always keeps a certain amount of disk space free (default 10GB). However, if the actual disk size is ~= SRC_REPOS_DESIRED_FREE_GB, then gitsever will delete all of the repos on the instance as part of the cleanup process. This forces gitserver to reclone all those repos again, which results in bad/broken UX.
One way of fixing this is to make the cleanup threshold percentage-based instead of a fixed number.
