Partially disable rule mode on parsing error for scan execution policies

Why are we doing this work

• currently when there is a yaml parsing error, the entire rule mode disables, which could be overkill (e.g. if the parsing error is because of a rule, then the action section should not have to be disabled)

Non-functional requirements

• Documentation:
• Feature flag:
• Performance:
• Testing:

Implementation plan

• investigate/create POC compartmentalizing the disabling of rule mode on a parsing error so that not all of rule mode is disabled when only one section has an issue
  • modify from_yaml methods for all policy types (e.g. scan_result, scan_execution, pipeline_execution and any other working policy) so that the errors provide the section/s that broke.
    • current error when parsing fails { error: true }
    • potential future error when parsing fails { action: false, rule: true, settings: false } where true indicates there was an error and the component should be disabled so that we can swap out the checks in the component :disabled="hasParsingError" for :disabled="parsingError[component]
• discuss POC with group and implement if agreed upon
• implement for scan execution policy
