Add support for F# templates

[Aaronontheweb]

We should have some dotnet new templates for F# users - and we should probably split this repository into separate C# / F# folders so they can each be maintained separately

[richardjharding]

I'd be happy to help port the existing ones to F# - I guess they could then be iterated on to make more F# idiomatic ?
Do you envisage a structure like the following

src/csharp/AkkaConsoleTemplate
src/fsharp/AkkaConsoleTemplate

Would that work with build.package process?

[Aaronontheweb]

@richardjharding that would work great - the WebAPI template we should not do anything with right now because I need to do another round of simplification with it, but the Console template and the Streams template are good to go for porting to F#
That folder structure works great too - make sure you update

akkadotnet-templates/scripts/test-templates.ps1

to include testing for the new templates!
