Show vulnerability report specific to a agent-managed cluster

Why are we doing this work

• Users will want to view the vulnerabilities of an agent-managed cluster

Relevant links

• Design

Non-functional requirements

• Testing

Implementation plan

• frontend Display the vulnerability_report component under the security tab in the javascripts/clusters/agents/components/show.vue component (!76713 (merged))
  • don't use vulnerability report because it would require too many conditionals. Use the vulnerability list and filters separately instead
• frontend ensure only that cluster's vulnerabilities appear
