* Update docs/submodules/oom/offline-installer.git from branch 'master'
to
4ea85321ebdd8b24b3cb732776e3847a03c993e7
- Merge changes from topic "kubernetes-inventory-groups"
* changes:
Add etcd group support to rke role
Add kubernetes-etcd group
Make rke to use new group structure
Add kubernetes-node group for workers
- Add etcd group support to rke role
Etcd cluster is now placed in members of kubernetes-etcd group instead
of kubernetes-node.
Due to defaults, it means infra is the only etcd
by default.

- Add kubernetes-etcd group
This group will contain kubernetes etcd cluster.
It is separated from kubernetes control plane and, especially, nodes.
There are of course no restrictions as to which
machines can be etcd.
Default is infrastructure-server.

- Make rke to use new group structure
Rke playbook/role is modified to take advantage of the new group structure.
Namely, all members of kubernetes group are treated as cluster members
independent of their role.
The role itself is selected in cluster.yml.j2 template
based on actual membership in either kubernetes-node
or kubernetes-control-plane group.

- Add kubernetes-node group for workers
Moved all kubernetes nodes from the kubernetes to kubernetes-node group,
and made the kubernetes group a parent of both kubernetes-node and
kubernetes-control-plane.
The reason is that we still need to have separate groups for
control planes and for nodes, but some
operations are performed equally on any kind of kubernetes
cluster member, and currently one would need to separately include all
related groups one by one. Example of
such common operation is installation of docker, that was not
performed for kubernetes-control-plane group, so that
docker was not installed on control planes that were neither infra nor nodes.
The side effect of this change is that if infrastructure
server is also a cluster member, it lands in a kubernetes group by default,
and node specific setup would be performed on it.
For that reason, playbook is modified to perform this setup on all
kubernetes cluster members except the infra server.
