##### OS / ENVIRONMENT
<!--
Information about the environment if relevant, N/A otherwise

##### SUMMARY
<!-- Explain the problem/feature briefly -->
When an existing physical network in a zone is deleted it is not marked as
'Disabled' , vlan table entries are not removed, user_ip_address entries and
not updated as removed ( with public traffic). These stale records affects new
VPC VR public IP association. VR gets created but the public IP is not
configured on the public interface intermittently. In addition to this one
there could be other potential impacts as well.
##### STEPS TO REPRODUCE
<!--
For bugs, show exactly how to reproduce the problem, using a minimal
test-case. Use Screenshots if accurate.
For new features, show how the feature would be used.
-->
<!-- Paste example playbooks or commands between quotes below -->
~~~
1. Delete the existing physical network having the public traffic in the
zone
2. Create a new physical network using the same VLAN, IP ranges for the
public traffic.
3. Deploy a new VPC.
4. Observe that ( intermittently) the public IP allocated is missing on the
VPC VR guest OS interface configuration.
5. Observe that the Source NAT is not working.
6. Observe that the 'com.cloud.agent.api.routing.IpAssocVpcCommand' is
missing in the VR StartCommand.

##### EXPECTED RESULTS
<!-- What did you expect to happen when running the steps above? -->
~~~
The deleted physical network doesn't leave stale records in the DB.
Public IP should be configured on the VPC VR.
~~~
##### ACTUAL RESULTS
<!-- What actually happened? -->
<!-- Paste verbatim command output between quotes below -->
~~~
The deleted physical network leaves stale records in the DB.
Public IP is missing on the VPC VR.
