*: new cli-nodes for BGP SRv6 VPNv4 (step4)

This commit add just CLI-nodes for MP-BGP VPN configuration
with SRv6 backend rather than MPLS. Actual configuration cli
will be implemented after this commit.

Example Configuration follow.
This cli design is based on Cisco IOS-XR but actual cli
tree design is defferent between FRR and Cisco.
It's just based on cisco.
