Register the dotnet jupyter kernel to use in ADS

[Mungoid]

Is your feature request related to a problem? Please describe. Would like .Net kernel as an option like in Jupyter notebooks

Describe the solution or feature you'd like Want to be able to choose C# or F# as a kernel in notebooks

Describe alternatives you've considered I use jupyter notebooks and nteract currently with the dotnet kernel. I have dug around the ADS code to see if i can tie it to the dotnet jupyter kernel, but have not had any luck figuring out how to do so.

Additional context I generally use ADS for pretty much everything but my company is primarily a .Net company so I would like to be able to use C# code instead of Python. I currently have the dotnet Jupyter kernel installed but switch to using Jupyter notebooks or Nteract if i want C#. Doing this makes things more complicated when trying to share with coworkers that also use ADS.

This is on our radar, and I've been working on this as I've had time.

If the dotnet kernel is installed, users can leverage the dotnet kernel in 2 ways, if the following setting is checked:

• If users open a previously saved dotnet kernel notebook, ADS should be able to load these kernels
• If users go to new notebook, the dotnet kernels won't show up until users select a Jupyter (i.e. any kernel other than SQL) kernel. After that, you should be able to see the dotnet kernels in the dropdown (this bug is why we haven't turned this functionality on by default).

Additional note on Impact - There have been multiple requests to use multiple languages in the same notebook from livesite engineers.
