Add preprocessing for store objects and add normalization for rbac

Motivation

https://datadoghq.atlassian.net/browse/AGENTONB-2643

Additional Notes

Anything else we should know when reviewing?

Minimum Agent Versions

Are there minimum versions of the Datadog Agent and/or Cluster Agent required?

• Agent: vX.Y.Z
• Cluster Agent: vX.Y.Z

Describe your test plan

Using a prior operator version, check clusterroles and roles for their permissions. Update the operator and check that the permissions are equivalent. This can be done using orchestrator explorer compare for simpler rbac or by comparing the describe output of the two different operator versions:

# run with prior operator version and operator version with this pr and compare outputs
$ kubectl describe clusterrole datadog-agent-cluster-agent
