#4490 new defect

kea-dhcp4 subnet4_select() hook is called prior to any other hook point

Dhcpv4Srv::acceptDirectRequest() calls Dhcpv4Srv::selectSubnet() as part of determining whether or not the packet should be accepted. The selectSubet() method in turn, calls the the subnet4_select hook point. The issue is that this means the subnet4_select hook is a: called before any other hook, making the call order wrong and b: called more than once, as selectSubnet() is invoked prior to processing a packet, once it has been selected.
