We would like to add a label to `kubevirt_vmi_phase_count` metric based on the information reported by the guest agent in the VMI's status.guestOSInfo.

The following labels should be added to the metric: guest_os_kernel_release, guest_os_machine, guest_os_name, guest_os_version_id

Which correspond to following status.guestOSInfo fields: kernelRelease, machine, name, versionId
