Reasons:

• [ ] json.load for --artifacts parameter does not perform snake_case translation for keys of input dictionary
• [ ] Validator was missing onto --artifacts that is causing artifactId from json input was not converted into fully qualified resource Id

Fix is included https://github.com/Azure/azure-cli/pull/2997/commits/50aa53135d86cc2a6582c6e911d332bff5aa9990#diff-c2f6f2cef5de551e95ad8ca6a94f1f13R71
