Description

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.
