Daniel Hilst 9da497cac4 fix(dhcp): let Kea start, let ISC refuse, and ask for what is asserted
Three things the wire cases turned up, only the first of which is xCAT
answering a client wrongly -- the other two never got as far as an answer.

kea-dhcp4 would not start at all. The ONIE class named option "www-server",
which xCAT's dhcpd.conf declares as code 114 = string but which means the
standard option 72 to Kea -- a list of IPv4 addresses, so an installer URL
in one is a configuration error and the whole Kea pass of the wire cases
never ran. Naming the code instead says the same thing to both.

ISC answered a request for an address on a network it has never heard of
with silence, where the spec says DHCPNAK, because "authoritative" was
written into each subnet declaration and read from the subnet the
requested address belongs to -- which, for this case, is none of them. It
is now global as well, which is what Kea's authoritative:true already
covered.

The remaining two were the cases asking the wrong question. ISC sends an
option when the client asks for it, so an ONIE case that never put 114 in
its parameter request list could not see it however the class was
written; and the common-option case announced a PXEClient vendor class
while asserting the cluster's lease time, which is the ten-minute
firmware lease of S-51 rather than S-50. S-50 now says which clients it
is about.
