Add cpu speed detection methods

[BartJM]

Description

This PR ads two additional methods to detect cpu speed on kvm hosts. This will improve the speed detection on AMD Epyc cpu's. For cpu's where the Ghz is in the model name no change will occur. For other cpu's the detected cpu speed ca change to the max Mhz of the cpu.

1. A match on the CPU max MHz value from lscpu
2. An additional sysfs file scaling_max_freq

Fixes: #6914

Types of changes

• [ ] Breaking change (fix or feature that would cause existing functionality to change)
• [ ] New feature (non-breaking change which adds functionality)
• [ ] Bug fix (non-breaking change which fixes an issue)
• [x] Enhancement (improves an existing feature and functionality)
• [ ] Cleanup (Code refactoring and cleanup, that may add test cases)
• [ ] build/CI
• [ ] test (unit or integration test code)

Feature/Enhancement Scale or Bug Severity

Feature/Enhancement Scale

• [ ] Major
• [x] Minor

How Has This Been Tested?

Tested on a kvm host with an AMD EPYC 7601 cpu.

• With normal agent start the cpu speed is detected as the expected 2200Mhz.
• Removed the cpu max Mhz line from the lscpu output and restarted agent. The detected speed is still the expected 2200Mhz.

On an kvm centos8 vm without the lscpu matches and neither file the agent still falls back on host capabilities.

@DaanHoogland @BartJM looks like some unwanted commits were added to this PR, probably due to the force push in the main. @DaanHoogland, could you take a look on this?

@BartJM , you want to execute

git rebase --onto main c087de4adfe0db02802ec4fe0929a5b3d6dfba2a 0ceff7f5b4cfdd2b2f26591d933eb112d8cf2329

and force push (git push --force) your branch. or alternatively start a new branch and git cherry-pick 0ceff7f5b4cfdd2b2f26591d933eb112d8cf2329 on that new branch. Then rename it to replace the branch in this PR or start a new PR.

@kiranchavala can you check thsi and see if this fixes #9819

@kiranchavala can you check thsi and see if this fixes #9819

Sure @DaanHoogland I will take a look

[Pearl1594]

@BartJM could you rebase this to 4.20. So that we could have this in the 4.20.1 release. Thanks.

@Pearl1594 , cc @kiranchavala , these errors seem consistent on 4.20, lately. Can we merge this?

@DaanHoogland I have seen these exact failures in other PRs. I think we are safe to merge here.
