Current Behavior

The consumers does not support inputs that contain a modifiedIndex field.

The core.config.new(“/consumers”, cfg) does not include an item_schema input similar to the other resources because consumers needs to handle both consumer and consumer_credential resources under the same key.
It just passes in a function that checks the schema and determines the resource type by key and performs specific checks if needed.
The additional field modifiedIndex that we have now introduced in config_yaml cannot be applied to the internal check function of consumers, so the check will output an error.

Expected Behavior

Consistent with other resources.

Error Logs

invalid consumers at index 0, err: additional properties forbidden, found modifiedIndex

Steps to Reproduce

1. Use the API to submit a consumer containing the modifiedIndex.
