We started to add mitigations for Spectre, Meltdown, MDS and similar vulnerabilities, which usually require a fixed microcode and so they are identified as different CPUs. Until now we had separate types for them which made it hard to maintain and follow. Let's introduce a "Secure" type as a rolling variant which will have the latest and greatest of mitigations. This includes additional warnings when running VMs and Hosts were previously Secure but after an update they're no longer "secure enough".
Verified the RFE on RHV 4.4.1-11 with hosts RHEL 4.4 and RHEL 4.3. The tests are attached in the Polarion link.
