Raspberry pi ARM support

[OlafRadicke]

Hi!

Here is a patch as a suggestion for adding the raspberry pi ARM support:

master...OlafRadicke:master

I hope it is useful.

Best regards,

I also needed alternative architecture for the installation, I used to hardcode the value myself, but wouldn't it be easier to maintain just to replace architecture with a variable and globally default to x64 provide all variations inside documentation and a URL to the Microsoft page defining supported systems/architectures? It's sad that there are so many variations to specify the same architecture by different vendors (so not easy to use facts gathered by ansible setup module) :/
