BREAKING CHANGE: `chrony.removed` replaced by `.clean` states.

* Run `chrony.config` as workaround
  - `.config` not called by `chrony`
* Disable `fedora` for the time being due to `systemd` issue
  - Refusing to accept PID outside of service control group,
    acquired through unsafe symlink chain: /var/run/chrony/chronyd.pid

Allows the use of gitfs mountpoint and renaming hte folder without
the need to manually update any of the paths

When calling chrony.removed salt ensures the service is stopped
and the package has been removed.
