Daniel Hilst 26e8e277ef fix(dhcp): give both backends one answer for where a node is sent ...

siaddr comes from noderes, in an order neither backend had right. ISC
read xcatmaster only for petitboot and onie, so every other node in a
hierarchical cluster was sent to the management node rather than to its
service node -- and even for those two the address went into the URL
without going into siaddr, so one reply named two different machines.
Kea read xcatmaster for every node, but when nothing named a server it
used my_ip_facing rather than the subnet's value, which is a different
answer whenever networks.tftpserver names a third machine.

Both now read next_server_for_node: the node's tftpserver, then its
xcatmaster, then -- only for the methods that build a URL and so need an
address in hand -- the interface facing the node. A node that named none
of them inherits the subnet's value, which ISC states in the subnet and
Kea states by leaving next-server out of the reservation.

An xcatmaster that does not resolve is now an error on both rather than
silence on one: it is a misconfiguration, and sending the node somewhere
else instead hides it.

Appendix A rows 26 and 27. Unlike the rest, these two are not in
xcat-internal#175 -- the wire cases found them.
