The userspace proxy does not have any ratelimiting and when many services are used will hammer iptables every time a service or endpoint change occurs. Instead build up a map of changed services and process all those changes at once instead of each time an event comes in. This also ensures that no long-running processing happens in the same call chain as the OnService* calls as this blocks other handlers attached to the proxy's parent ServiceConfig object for long periods of time. Locking can also now be simplified as the only accesses to the proxy's serviceMap happen from syncProxyRules(). So instead of locking in many functions just lock once in syncProxyRules() like the other proxies do. https://bugzilla.redhat.com/show_bug.cgi?id=1590589 https://bugzilla.redhat.com/show_bug.cgi?id=1689690
