[c-nsp] L2VPN between ASR920 and Juniper

JunOS by default uses VC type 5 for a physical port, and VC type 4 for
a VLAN-based subinterface. Seems quite logical to me.

JunOS can be configured to explicitly set the VC type, and also to
*ignore* VC type mismatch. 

We have lots of pseudowires between Juniper and Cisco equipment (though
no ASR920). Works just fine.
