Failover for adding proxy when line exists in file (#5751)
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.

fix kube-proxy server address when local apiserver lb is disabled (#5730)
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.

Upgrade container-engine after draining (#5601)
* 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.

f1498d4b53 fix OWNERS file (#5359)
Initially this was to fix a mis-indented approvers key. However, it turns
out that 'oilbeater' is not a member of kubernetes-sigs nor
kubernetes-incubator (the org this repo was migrated from). Thus this
OWNERS file is failing prow's validation check.

As a workaround I've opted to move them to emeritus_approver, which
isn't valiated and can be used as a hint for other approvers in this
repo
