Rewrite backend build/development/publish system - providing streamlined development and production deployment

[johncclayton]

The use of docker is technically a great idea but makes it harder to debug / view log files etc. It feels like a large hammer (and everything else is a nail).

I've wanted to automate the entire build process for some time; so this ticket sets out to:

• automate the sd-image creation
• streamline development / production deployment - it will all be the same
• remove Docker entirely from the project
• use Raspbian images instead of Hypriot (to speed new board support)
• use Terraform to provide AWS based build box hosts
• document all the above

There is a LOT of benefit to the way we are building the SD images, some of these are:

• more immediate support for new Raspberry Pi boards
• simplicity - at the end of the day our sd-images are just Raspbian Lite modified builds
• easier setup for debugging; nothing is isolated within a container
• consumers can still just "plug it in", there's no requirement to download more stuff - it's all been done
• STILL fits on a 4GB card
• the project retains total control over the entire image, so less surprises and a more consistent experience across the board from consumers (just get it working for me!) to development (hey look, the dev env is actually a subset of the production env - not a completely different one).

I've been working on this for a couple of weeks now at nights - progress is GREAT.

Don't get me wrong - Docker rocks - it just feels like the wrong tool for this particular job.
