[receiver/vcenter] add vcenter vm cpu usage metrics

[schmikei]

Description: Trying to resolve #19733 with knowledge of how the test harness works.

Did change to not report CPU usages/utilizations of 0 since this information is not pertinent and most likely is a turned off/ unreachable VM. For larger environments it saves costs OOTB by ingesting less useful metrics.

Link to tracking Issue: Resolves #20895

Testing: Updated Test Harness

Documentation: Updated metrics documentation

I'll take this but would like to aforemention the great amount of research and time @padraicbc has contributed to this. I just feel as though this is the quickest way to get this change in.
