[FEATURE REQUEST]: Dotnet Backend IPAddress

**Is your feature request related to a problem? Please describe.**
Currently it is possible to specify a custom port for the Dotnet Backend. However it will only listen on the loopback address.

**Describe the solution you'd like**
Would it be possible to assign a specify the IP-address as well (e.g. 0.0.0.0 for all IPv4 addresses)?

**Additional context**
This would make things easier, if using .NET for Apache Spark with a docker container (e.g. https://hub.docker.com/r/3rdman/dotnet-spark) for example.
