Honour GS use_ext_dns and redundant VR VIP
This patch addresses two issues:
- 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.
