Bug Description

Environment:
Queens: Nova, Neutron, Designate(External DNS)
Network has dns_domain set

Steps to reproduce:
1. Create a port from the network
2. Create an instance with the port attached, dns_name in the port will be updated and a record will be created in user's recordset.
3. Delete the instance.
4. Check the port, the dns_name is reset to empty but the dns record under user's zone is not removed.

This also affects the usage of orchestration components like Senlin/Heat since they usually create a port separately and then create an instance with the port.

This bug was filed in Neutron before and has more debug information: https://bugs.launchpad.net/neutron/+bug/1741079

Fix port dns_name reset

    When external DNS service is enabled, use user's context to request
    dns_name reset instead of using admin context. The dns record need
    be found in user's zone and recordset.

    Also add show_network to NeutronFixture as needed in functional
