/**
* Implement the Pipeline Pattern
*
* More information and detailed example in (TODO add link to technical doc when ready)
*
* Some plugins contains custom logic to enrich data provided by other plugins or components.
* For instance, the row grouping plugin needs to add / remove the grouping columns when the grid columns are updated.
*
* =====================================================================================================================
*
* The plugin containing the custom logic must use:
*
* - `useGridRegisterPipeProcessor` to register their processor.
*
* - `apiRef.current.requestPipeProcessorsApplication` to imperatively re-apply a group.
* This method should be used in last resort.
* Most of the time, the application should be triggered by an update on the deps of the processor.
*
* =====================================================================================================================
*
* The plugin or component that needs to enrich its data must use:
*
* - `apiRef.current.unstable_applyPipeProcessors` to run in chain all the processors of a given group.
*
* - `useGridRegisterPipeApplier` to re-apply the whole pipe when requested.
* The applier will be called when:
* * a processor is registered.
* * `apiRef.current.requestPipeProcessorsApplication` is called for the given group.
