## What is the purpose of the change
This PR proposes to discard watermarks when feed a datastream into iteration
body since watermarks are not correctly processed in iteration module.
To avoid the possible bugs, we plan to add a java doc to explain that
`flink-m-iteration` module cannot deal with watermarks for now. We also leave
it as a TODO here and plan to support it in the future.
