CORD-2870: Bypass DHCP leasequery without learning routes.
Changes:
* Add configuration flag to disable old leasequery routing/learning flow
* Route leasequery (v4 and v6) responses to an originator
* Fix NPE and BufferOverflow exceptions in Dhcp6LeaseQueryOption
* Make Dhcp4/Dhcp6HandlerUtil classes static
* Fix codestyle issues
Change-Id: Ic9e527d73a226e7f1f544dab9fb98398b85c5460
