@NicoK , I found most of the codes in this PR are already merged into
master by commit `0093bcbe771f296baf3857ef15fe7ec9b22bbc34` in your
`FLINK-8425`. Maybe I only need to add the `config.md` in this PR.
> Add the switch for keeping both the old mode and the new credit-based mode

> URL: https://issues.apache.org/jira/browse/FLINK-8458
> Project: Flink
> Issue Type: Sub-task
> Components: Network
> Reporter: zhijiang
> Assignee: zhijiang
> Priority: Major
> Fix For: 1.5.0

>
> After the whole feature of credit-based flow control is done, we should add a
> config parameter to switch on/off the new credit-based mode. To do so, we can
> roll back to the old network mode for any expected risks.
> The parameter is defined as
> {{taskmanager.network.credit-based-flow-control.enabled}} and the default
> value is true. This switch may be removed after next release.
