kdc Allow a password change when the password is expired
This requires a rework on Heimdal's windc plugin layer, as we want
full control over what tickets Heimdal will issue. (In particular, in
case our requirements become more complex in future).
The original problem was that Heimdal's check would permit the ticket,
but Samba would then deny it, not knowing it was for kadmin/changepw
