K8s is moving away from the "master" terminology, so kubespray should follow the same naming conventions. See https://github.com/kubernetes/community/blob/65d886bb3029e73d9729e1d4f27422a7985233ed/sig-architecture/naming/recommendations/001-master-control-plane.md

* 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

* make calico api server manifest backward compatible with version older than 3.27.3

Add 3.28.1 checksums
Add 3.28.0 checksums
Change default version to 3.27.3

* change default calico version to 3.28.1

* Set mount type to DirectoryOrCreate for hostPath needed by Calico

We explicitly check for equality so customizing kubeadm_version does not
work at the moment.

Use only one variable instead.
