dhcpv6-server: T3493: add proper validation for prefix-delegation start/stop address
ISC DHCP server expects a string: "prefix6 2001:db8:290:: 2001:db8:29f:: /64;" where the IPv6 prefix/range must be :: terminaated with a delegated prefix length at the end. This commit changes the validator that the IPv6 address defined on the CLI must always end with ::. In addition a verify() step is added to check that the stop address is greater than start address.
