Notes

CentOS 8 is not supported in Bluval. We had a discussion about this topic last time and agreed that this should be documented somewhere

Reviews:
- 3556: Enable mandatory tests for REC
- 3550: Use docker host network for containers
- 3558: Support password ssh auth for all robot tests
- 3561: Add a new variable Robot loglevel
- 3562: Remove inactive committers
Lynis/Vuls automation
Debugging support: new very simple test cases like
- Ping to host
- Ssh access to SUT
- Volume mount
