Enabling IPv6 release notification

This feature enables the DHCPv6 relay agent to send a Release message to the DHCPv6 server after it deletes a DHCPv6 relay entry. After the DHCPv6 server receives the message, it reclaims the IPv6 address or prefix and marks the lease as expired.

If you do not enable this feature, the DHCPv6 relay agent will not send a Release message after it deletes a relay entry.
