Flushing the dosing pumps using the Growee App

This feature allows the user to select a signal or multiple pumps.
The selected pumps will run for 20 seconds each.

It can be used in situations where the user needs to replace nutrients,
and would like to clean the pump tube or run cleaning fluid inside the tube.

In the case of pH up / down pumps,
it is useful if the user needs to run the fluid through the tube.
