NuGet v3 repositories should show the correct URL to use in nuget client configuration

When using a NuGet v3 repository in a client such as visual studio or nuget.exe it is necessary to append "/index.json" to the end of the URL to make it work.

Currently the UI of Nexus Repo does not do this, it instead shows the base URL of the repository.

Expected: Somewhere in the UI the correct URL to use in client configuration should be clearly shown. E.g, http://localhost:8081/repository/nuget-group/index.json

If this can't be in the main URL then it should be shown near it somehow.
