Gateway_less_Fwd: Auto explicit creation of "vhost0" interface at provisioning time to apply SGs for gateway less forwarding feature

[Chandra Sekhar Reddy Mallam]

Auto explicit creation of "vhost0" interface at provisioning time to apply SGs for gateway less forwarding feature.

As part of gateway less forwarding, we will allow security groups to be applied on "vhost0" interface. So, this mandates explicit creation of "vhost0" interface. Right now, user is manually creating "vhost0" interface for each virtual-router. This can be taken care by provisioning scripts internally.

Current manual steps
--------------------
>>> vnc_lib.virtual_routers_list()

>>> nodek11_vr = vnc_lib.virtual_router_read(id="82b1a0c6-fd7b-402b-b5b1-2e8b0cc69bdc") # Vrouter

>>> vmi1 = vnc_api.VirtualMachineInterface(name="vhost0", parent_obj = nodek11_vr) # Parent is vrouter object

>>> ipfab_vn = vnc_lib.virtual_network_read(id="bbd1ac2b-dd1a-465b-949c-8bd904e3b81b")  # IP Fabric VN

>>> vmi1.set_virtual_network(ipfab_vn) # Provider network is IP-Fab

>>> vnc_lib.virtual_machine_interface_create(vmi1)
