    @zhijiangW can you rebase the new changes? The previous implementation got merged and from the comments I see here, there might have been some changes since then which should be applied as well.

> 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.
