[MEDIUM] config: automatically find unused IDs for proxies, servers and listeners
Until now it was required that every custom ID was above 1000 in order to
avoid conflicts. Now we have the list of all assigned IDs and can automatically
pick the first unused one. This means that it is perfectly possible to interleave
automatic IDs with persistent IDs and the parser will automatically allocate
unused values starting with 1.
