Done: * implement autosnapper that asserts interval between snapshots * implement pruner * job pull: pulling + pruning * job source: autosnapping + serving TODO * job source: pruning * job local: everything * fatal errors such as serve that cannot bind socket must be more visible * couldn't things that need a snapshotprefix just use a interface Prefixer() instead? then we could have prefixsnapshotfilter and not duplicate it every time... * either go full context.Context or not at all...? just wait because community climate around it isn't that great and we only need it for cancellation? roll our own?
