jenkins/build tox testing for cephfs-shell

Not sure who to direct this to so asking here. Varsha Rao has a PR [1] to add tox testing for the cephfs-shell as part of the build testing. Unfortunately it seems this isn't done as part of the jenkins build, probably because cephfs-shell is not an install target for most platforms due to dependency issues. cephfs-shell is currently only a valid target for Ubuntu 18.04+. I see that jenkins is using Ubuntu for the build [2] but I'm not immediately sure which flavor. Maybe enabling cephfs-shell builds is just something that needs turned on the CMake flags for the jenkins build (-DWITH_CEPHFS_SHELL)?
