Now multiple sections ending with `services` can be defined for each in pillar
and all of them will get merged into one service block in the zone. The goal is
to keep backward compatibility while allowing different services to be defined
in different pillars. So basically have various parts of the pillar affecting
the firewall without need to define everything centrally. Helpful for the
exceptions to the rules.
```bash
firewalld-formula$ yamllint -s .
