zebra: show interfaces in a specified VRF or all VRFs

The following commands only show interfaces in the default VRF:
    show interface
    show interface IFNAME
    show interface description

New options are introduced to show interfaces in a specified VRF:
    show interface vrf N
    show interface IFNAME vrf N
    show interface description vrf N

or all VRFs:
    show interface vrf all
    show interface IFNAME vrf all
    show interface description vrf all
