Add an option to allow AXFR of zones with a different (higher/lower) serial. #5169

Short description

Atm the AXFR of a zone stops if the serial is moving backwards and signatures start to expire. This is a very common problem in setups where the nameserver is secondary for many customers. Not everyone is a dns expert ;)
With this option it is possible to tell pdns to axfr the zone if the serial on the slave is different (higher/lower) from the one on the master.
