openstack zone create debuntu.foo. --type SECONDARY --master 10.9.95.132
### Expected result ###
Secondary zone is created and ACTIVE
### Actual Result ###
Secondary zone gets into the ERROR statuses + Error in log

Ok, so this is a bug in the "dnspython" library designate uses.
Version 1.16 which you had installed has:
if mexpiration is None or mexpiration > expiration:
mexpiration = expiration
Which is broken.
Version 2.0.0rc1 has:
(https://github.com/rthalley/dnspython/blob/v2.0.0rc1/dns/query.py#L925)
if mexpiration is None or \
(expiration is not None and mexpiration > expiration):
mexpiration = expiration
Which works.
** Affects: dnspython3 (Ubuntu)
Importance: High
Status: Confirmed
