### Expected Behavior

VRF lite configuration is applied to border gateway. 

### Actual Behavior

Task fails but VRF is actually created in NDFC, but not attached to the Border Gateway. The VRF-lite extension is also saved in NDFC database but, before the VRF can be attached and given the role of the device includes border gateway, the extension type (vrf lite + multisite) must be selected before VRF can be attached.

### Steps to Reproduce

Attach a VRF with VRF-lite enabled to a device with border gateway role.
