Description

• On every CLI scan with image referencer results, checkov would now always create the image cached results reports so we can save the results in the platform.
• For that reason the variable CHECKOV_CREATE_IMAGE_CACHED_REPORTS_FOR_IR is not needed anymore (always true), henced removed from the tests.
• Whenever the variable was true we were calling the cache twice, so I reduced it to one call and then the result is passed as a variable to the two relevant functions
