Updating and improving this code base

[flyhard]

I have been working on making this a bit better suited for my 4 raspberry pi cluster.

I tripped over consul servers running on the followers while also all followers should have consul clients. Rerunning the play would mess up the cluster. Still need to do some more improvements with regards to replaying if consul changes, but this is already a nice improvement.

I am also looking into making this not dependent on raspberry platform. I am considering adding some nomad nodes on VMs later.
