NetworkInterface Detachment Failure

[so-sahu]

Describe the bug
The NetworkInterface detachment process is not functioning as expected. After attempting to detach a NetworkInterface, it is successfully removed from the store but remains present in the DomainXML.

To Reproduce

1. Create a machine with nic.
2. Detach the nic.
3. Verify domain machine DomainXML. nic is not getting removed.

Expected behavior
The NetworkInterface should be successfully unplugged from both the store and the DomainXML.

@Rohit-0505 we will have probably wrong logic for manage status of nics. We have similar issue for volume: #144
