More interface apps

Here are some additional sample apps for interface configuration.  They complement those posted recently for IPv6.  You can find the sample apps at:

https://github.com/CiscoDevNet/ydk-py-samples/tree/master/samples/basic/ydk/models/ifmgr

 Note that these apps include interface configuration:

• nc-create-config-ifmgr-30-ydk.py - virtual interface (lo0)
• nc-create-config-ifmgr-34-ydk.py - physical interface (ge0/0/0/0)
•  And configuration for link status messages:
• nc-create-config-ifmgr-20-ydk.py - default message behavior
• nc-create-config-ifmgr-22-ydk.py - disable link messages
• nc-create-config-ifmgr-24-ydk.py - link messages for logical interfaces

 Make sure you review the README file for how to use these apps.  You'll find it at:

 Enjoy!
