Fix(eos_designs): Fixing empty SVI generation on node without ip_address (WIP)

[Vibhu-gslab]

Change Summary

Configure an SVI when we also have an ip_address for that node.
All others should only get the VLAN (not the interface vlan)

Checking for ip_address before creating SVI, also added a knob to retain old behaviour.
