* Simplify docker systemd unit
systemd handles missing unit by ignoring the dependency so we don't need
to template them.
* Remove RHEL 7/CentOS 7 support
- remove ref in kubespray roles
- move CI from centos 7 to 8
- remove docs related to centos7
* Remove container-storage-setup
Only used for RHEL 7 and CentOS 7
* Remove leftover files for Coreos
Coreos was replaced by flatcar in 058438a25 but the file was copied
instead of moved.
* Remove workarounds for resolved ansible issues
* boostrap: Use first_found to include per distro
Using directly ID and VARIANT_ID with first_found allow for less manual
includes.
Distro "families" are simply handled by symlinks.
* boostrap: don't set ansible_python_interpreter
- Allows users to override the chosen python_interpreter with group_vars
easily (group_vars have lesser precedence than facts)
- Allows us to use vars at the task scope to use a virtual env
Ansible python discovery has improved, so those workarounds should not
be necessary anymore.
Special workaround for Flatcar, due to upstream ansible not willing to
support it.
