move things around a bit () 
* keep ./services for instances

./profiles is for config-only modules

./services are like profiles, but configure a single instance of a
service. Those are fronted by Nginx as the load-balancer and have a DNS
entry as well.

* ci: build build03 as well

* move hydra to services

* move matterbridge to services

* move marvin-mk2 to services

* build01: share the remainder profiles

* build02: use the nix-community-cache

* fixup kexec

* rename profiles to roles

* README: sync with reality
