On redundant VR setups, the primary resolver being handed out to instances is the guest_ip (primary IP for the VR). This might lead to problems upon failover, at least while the DHCP lease doesn't update (because the primary resolver will be checked first until times out, however it'll be gone upon failover).
If Global Setting use_ext_dns is true, we don't want the VR to be the primary resolver at all.
firewallrules implemented sperately from networkacl (ugly but best that can be done ATM)
Some refactoring in CsDHCP as it made no sense to do it that way anymore
processmonitoring implemented
Domain not correctly sourced in VR
