Build best-practice suppression groups and replace prd selectors

[webtonize]

As a PO I want transparency in the objects selected for inspection so users can have a clear understanding of the scope of the audit. Therefore I want the selectors used for inspecting only production resources deprecated and rules adapted accordingly. To help users get started quickly a decent suppressiongroups yaml should be offered as a replacement.

Acceptance Criteria

• PSRule Production selectors removed from the codebase
• Rules changed to inspect all objects formerly scoped by the selectors
• Example YAML and instructions for a best-practice set of PSRule suppression groups
