Description of problem: Heketi tries to use lsof to automatically help with the debugging of umount failures. However, lsof is not present in server container images as far back as 3.11.0. We lose a helpful behavior from heketi without having the tool present, forcing the admin/support to do extra work. Including the tool is very low cost to us.
