Create a consumer named <consumername> in the consumer group <groupname> of the stream that's stored at <key>.
Consumers are also created automatically whenever an operation, such as XREADGROUP, references a consumer that doesn't exist.
This is valid for XREADGROUP only when there is data in the stream.
