Critical Description
It may be useful to allow different edge manager plugin types based on different requirements. In order to support this, we would need to support different plugins per edge for routing the events on that edge. A motivating scenario is when a custom plugin from an older release of a downstream project is using older API's while the latest release of that project has moved on to newer API's. This would allow both old and new releases to work with the latest Tez framework as optimally as possible.
