Standard NSM for all Endpoint

[younus2019]

We are working on implementation of Cisco NSM example for multi cluster. we are able to deploy helloworld client and vl3 endpoint and was able to make communication between nodes.
After that we are trying to implement additional endpoint in the clusters but facing some issues because the cisco example is installing the nsm that not supporting custom endpoint. And if
we try to install nsm manually by following nsm docs then custom endpoint is working but vl3 example of cisco is not working.
