Tracking: enable EVE services to run as a series of containers not in a device

[deitch]

This is a tracking issue.

EVE currently runs as a series of services in containers - mostly a few and one big one called pillar - on a device.

We have two goals:

1. Extract all of the services from inside a device (real or virtual), so we can run them as a set of containers on any linux host. For example, use docker compose to run them all directly on a laptop or an AWS VM, not inside a physical device or qemu virtual device.
2. Enable each service to run standalone without any other services. For example, run downloader all by itself.

This is the tracking issue for the first. It is a place for design discussions as well as the checklist for what is needed. Each item on the checklist should have a PR link next to it.

• [ ] create compose file
• [ ] create run target in Makefile
• [ ] update watchdog so it doesn't try to reboot when running in compose
• [ ] more points here @rvs
