CMP-2615: Add a check aggregate to the compliance scan metadata

Implement a total check count as an annotation of the ComplianceScan, we will add an annotation compliance.openshift.io/check-count
to every compliancescan object when a scan is in done state. Noted: This annotation is removed when a new scanPhase begin.
