Summary: Old SG rules created by CNO on Kuryr bootstrap not removed on upgrade

Severity: high    
Priority: urgent CC: gcheresh, juriarte, ltomasbo, rlobillo

Whiteboard:
Fixed In Version: Doc Type: Bug Fix
Doc Text:
Cause: cluster-network-operator on Kuryr bootstrapping had no logic to remove deprecated security group rules when they get replaced by new ones. Consequence: On OCP upgrade the old SG rules were left on the SGs meaning that tightening them to increase security was not done on environments upgraded between 4.3.z releases. Fix: The fix is to make sure CNO is removing old security group rules. Result: The SG rules get removed, on 4.3.z upgrade pods are correctly getting the access to host VMs restricted.

Verified in 4.3.0-0.nightly-2020-05-18-043018 on top of OSP 16 compose RHOS_TRUNK-16.0-RHEL-8-20200506.n.2

In order to verify this BZ OCP4.3.0-0.nightly-2020-05-13-181621 was installed and CNO image was updated to the one included on OCP4.3.0-0.nightly-2020-05-18-043018, which includes the fix.
