📦 Docker containers for all local services 📦

[Terkwood]

Create docker containers for all rust services running on Raspberry Pi / ARM.

• fix up services start.sh
• Document redis_aggregator image build process
• use armv7 rust image, Don't use terrible repo checkout strategy
• LED status helper (Dockerize led status helper #102)
• sensor tracker (Dockerize sensor tracker, use rumqtt #94)
• pH ref calibration (📦 Dockerize & upgrade PH calibration service 📦 #101)
• redis aggregator

Redis aggregator image build process

It's overly complicated and still relies on debian. We should transition it to alpine in #99

Deferred work

#100: Use docker compose ∀ service containers

[Terkwood]

You can build the ARM docker image for redis aggregator on a Mac, e.g., then copy it over to your Raspberry Pi

You can read this helpful SO link about saving docker images.
