Code Review

This pull request introduces a plugin whitelisting mechanism to allow specific plugins, such as pai-easycv, to bypass the trust_remote_code security check. A new utility function filter_plugin_not_in_whitelist is implemented and integrated into the pipeline and trainer builders. However, a critical logic error was identified in both builders: overwriting the plugins variable with the filtered list removes whitelisted plugins before they can be registered and loaded. It is recommended to use a separate variable for the security validation to ensure whitelisted plugins are still processed.
