Configure inter-area ISIS SR with mapping server

A while back, we published a couple of sample apps for segment routing: 

• nc-create-xr-clns-isis-cfg-40-ydk.py - IPv4 ISIS Segment Routing
• nc-create-xr-clns-isis-cfg-41-ydk.py - IPv6 ISIS Segment Routing 

Here are four more sample apps for segment routing.  They all work in the context of inter-area ISIS, include both IPv4 and IPv6 routing, plus they illustrate mapping server configuration.

• nc-create-xr-clns-isis-cfg-50-ydk.py - IPv4 ABR with SR
• nc-create-xr-clns-isis-cfg-51-ydk.py - IPv6 ABR with SR
• nc-create-xr-clns-isis-cfg-52-ydk.py - IPv4 ABR with SR mapping server
• nc-create-xr-clns-isis-cfg-53-ydk.py - IPv6 ABR with SR mapping server 

You can review their GitHub commit for app details.
