[#1428] Configure DHCP servers to accept and use multiple reservations for the same IP address
This MR should introduce new global configuration parameter
ip-reservation-unique with a default value
true. When set to
false the servers will accept multiple reservations for the same IP address. Obviously, that has to correspond with the backends in use. If any of the backends does not support it, this setting should be refused. When in use, the allocation engine should also assume that multiple reservations can be returned for the given IP address.
