[Environment]

Charms 20.08
[Description]
After deleting a zone on a designate-bind backend, the zone
remains active until the zone purge producer task gets executed.
$ openstack zone show 98c02cfb-5a2f-xxxx
Could not find Zone
$ openstack zone delete 98c02cfb-5a2f-xxxx
Could not find Zone
mysql> select * from zones where id="98c02cfb-5a2f-xxxx";
Empty set (0.01 sec)

No zone was found by this criteria, therefore, the hard delete zone from the

didn't apply.
This delta is governed by time_threshold
https://github.com/openstack/designate/blob/89435416a1dcb6df2a347f43680cfe57d1eb0a82/designate/conf/producer.py#L100
which is set to 1 week.
### Proposed actions
1) Make the time_threshold shorter to a 1 hour span by default.
2) Don't list deleted_at zones in designate list operation.
