When I updated the HC and VPP version to 17.10 I am no longer able to mount VPP node to odl. I am getting warnings regarding unsatisfied imports for bunch of models from HC. see attached file for log output. 

Also the multi-naming-context has a bad revision and file name. It has a revision of 2016-4-11 but should be 2016-04-11. When this is fixed at least one of those warnings goes away. 

There are probably other issues with those models tat ave unsatisfied imports. Not sure if something changed in netconf or yangtool that could cause this issue.
