Support dynamic prefix in DHCPv6 Server
Most of the ISPs using dynamic IPv6 PD. Pfsense receive the prefix and can allocate a /64 prefix on LAN interfaces (Track Interface mode). Create a Tranking Interface like option in the DHCPv6 prefix delegation. Now Pfsense has some strong limitation if the IPv6 is dynamic.
Example: Pfsense receive /56 from ISP. This means 256pcs /64 prefix. Now prefix 0,1 can be used in LAN1 and LAN2. The unused prefixes (2-256) should be used by DHCPv6 PD Server to send prefixes to other routers.

This would be a very useful feature.
The prefix delegations handed out by the DHCPv6 Server are currently static only. If the prefix they are delegating out of is dynamic that means a manual update everytime it changes.
Allow the prefix delegation range to track another interface.
