Description

The current CI Docker image is based on Ubuntu 16.04. We already use 20.04 for the e2e tests. We can update the Docker image to a newer version to be on par with what we need in GitHub Actions (FLINK-33923).

This issue can cover the following topics:

• Update to 22.04
  • OpenSSL 1.0.0 dependency should be added for netty-tcnative support
  • Use Python3 instead of Python 2.7 (python symlink needs to be added due to FLINK-34195) 
• Removal of Maven (FLINK-33501 makes us rely on the Maven wrapper)
