IMO we already have a metric in vsphere-problem-detector that reports vCenter version and ESXI versions, we just need an alert for that.

There is some issue on our 6.7 vSphere env, no successful installation now.

Blocked by https://bugzilla.redhat.com/show_bug.cgi?id=2089153, hit twice in 6.7 vSphere env.

Verified failed on vSphere 6.7.2, there is no alert raised.

vsphere_esxi_version_total metric shows 6.7.2.
