Description

Update the 'extension points' on User-defined Sources & Sinks page (https://nightlies.apache.org/flink/flink-docs-master/docs/dev/table/sourcessinks/#extension-points) about how to integrate with source parallelism setting with their custom connectors.

Since no doc exist for the new interfaces introduced in FLIP-146, which is closely related here, we'll update doc to cover them as well.
