[S] Change in osmo-ci[master]: ansible: podman: use fuse-overlayfs

osmith has submitted this change. ( https://gerrit.osmocom.org/c/osmo-ci/+/37896?usp=email ) Change subject: ansible: podman: use fuse-overlayfs ...................................................................... ansible: podman: use fuse-overlayfs The default driver "vfs" leads to container crashes on heavy i/o load on our jenkins machines. Use "fuse-overlayfs" instead, which does not have these problems. Add a systemd service that creates /dev/fuse when the LXC container starts and configure the driver via ~/.config/containers/storage.conf. Note: when changing the storage driver, the previous storage database needs to be removed (~/.local/share/containers/storage/). I've done this manually before rolling out this change.
