Is your feature request related to a problem? Please describe.
Officially K8s 1.18.x end of support was 31.01.2021 but the newer version was released (1.18.16).
Our current version has a few vulnerabilities:
CVE-2020-8566
CVE-2020-8565
CVE-2020-8564
CVE-2020-8563

Describe the solution you'd like
Upgrade K8s to 1.19.x with dependencies: CNI plugins, dashboard, etc. Check release notes for that, deprecated things should be removed/updated.

Additional information
The Kubernetes project maintains release branches for the most recent three minor releases (1.22, 1.21, 1.20). Kubernetes 1.19 and newer receive approximately 1 year of patch support. Kubernetes 1.18 and older received approximately 9 months of patch support.
