docker_compose state for odroid1 and odroid2

[iancleary]

docker_compose_state: present or stopped

only run tailscale up docker exec if state == present

That way all the images are there, the compose files are there, but the services aren't running nor are they authenticated with tailscale.

perhaps this is a separate variable for whether or not the node is the primary.
then both have docker_compose_state: present to be more of a hot spare.
