The 'regexp' parameter matches last occurrence of a line starting with 'proxy=' and replaces it with the one defined in 'line' parameter. If no match - it works same way as before. This fixes resuming cluster deployments failed after that task (if there was no more than one line starting with 'proxy' in the yum.conf file - this condition should also be reassured with the change introduced here) eg. if they were initiated with Terraform.

refs #5277

As the issue describes, when no external or local load-balanced is used,
kube-proxy won't be able to contact apiserver at 127.0.0.1. So the
config map should be left as is.

exists role kubernetes/preinstall and not exists role container-engine

 error 'yum_repo_dir' is undefined

* Run 'container-engine' after drain.

Move possibly disruptive role 'container-engine' to run after the node
is drained.

As that role have to be run on non-cluster nodes as well (etcd and
calico-rr), and those nodes are not drained, add play for that case.

* Check if api is up before upgrade.

If container engine is restarted in previous role, api controller can
take some time to start. This check ensures api is up before upgrade.

- Add support for manage-security-groups flag
- Add support for internal-lb flag

* make cinder csi topology aware

* change feature description do better reflect whats being done

When kube-router is used as cni, rules might be added to the mangle table
to support external IPs. Therefore, mangle table should be flushed during
reset as well.

This 38688a44 change replaces the
value for dockerproject_.+_repo_.+ docker variables but their new
value was previously defined in other variables. This change removes
the dockerproject_.+_repo_.+ docker variables in favor of the older
ones.
