SR Shortest Path Tunnel Over RSVP-TE IGP Shortcut Feature Configuration

Two prefix family values of srv4 and srv6 are added to the igp-shortcut construct.

When enabled, the srv4 value allows IGP to resolve SR-ISIS IPv4 tunnels in MT=0 or SR-OSPF IPv4 tunnels over RSVP-TE LSPs used as IGP shortcuts.

When enabled, the srv6 value allows IGP to resolve SR-ISIS IPv6 tunnels in MT=0 over RSVP-TE LSPs used as IGP shortcuts.
