config/textfsm: created textfsm routes templates for sonic 4.2

- created sonic_routes_v42.tfsm: template specific for route command in
sonic v42 where entries contains the vrf id instead of the vrf name
- created sonic_vrf_show.tfsm: template to parse the output of the
ip vrf show command, useful to get the vrf name
