* fix(frontend): Introduce ALLOWED_ARTIFACT_DOMAIN_REGEX flag to prevent accessing undesired domains. Remove user input string from server response.
1. Remove user query parameter string from server response.
2. Introduce ALLOWED_ARTIFACT_DOMAIN_REGEX to allow configuration of allowed domains querying.
3. By default, ALLOWED_ARTIFACT_DOMAIN_REGEX is match all. Default configuration is meant to be demo purpose and not for production.
4. Users can provide ALLOWED_ARTIFACT_DOMAIN_REGEX environment variable to restrict object storage endpoint querying domains.
* add test
