Update test-cert CLI to include UZI, URA, and AGB parameters

Improved the test-cert command to specify UZI, URA, and AGB parameters instead of a single identifier. This change enhances flexibility and allows for a more precise definition of test certificates. Updated help text for better clarity and added comments to explain the format of the otherName field.
