Enhancement Request

Currently, EventMesh has the basic ability to transport event, but there are shortcomings in process/filter/monitor/xx event.

For example, if I want to monitor the number of specific events or just filter some events, I may need to change the code in runtime(It is not easy).

A better practice is to add a processor when I want to add a processing function, instead of change the core code.

Describe the solution you'd like

Using event processor chain to enhance EventMesh runtime.
