Implement service expiration

One way might be to use the gb_tree module and add expiration times as services are added. But assuming processes really are cheap as advertised, an interesting and simple first-pass solution is to spawn a process for each service when registered that waits to remove it. It would need to check before removing that the expiry has not been updated. There is also the problem that if the server crashes then these processes don’t have a way to restart. An eventually consistent approach could have a cleaner process that checks for expired processes once a minute, say, in addition to per service cleaners.
