This is an alternative to #566 that adds support for running container services using podman along with modified versions of @Firefishy's work to run welcome.openstreetmap.org as a container.
Unfortunately containers/podman#12778 means it's not currently possible to use
DynamicUserto run each container as a separate user so instead it edits/etc/subuidand/etc/subgidto reserve a block of user IDs for containers and then uses--userns=autoto allocate each container a group of IDs from that block.It also switches networking to use
slirp4netnsmode (which would be the default if we were running as a non-root user) which is probably a bit less efficient but avoids needing to add firewall rules which then cause issues with shorewall.
