This change removes ability to disable allocation new leases new
Renew/Rebind, specified in RFC7550. The behavior specified in this
RFC is the only supported behavior.

Also, fixed failing unit tests.

This test checks that the client can request allocation of the
prefix when it renews the existing IA_NA binding.

The DHCPv6 test client had to be extended to faciliate this.
