Pass in the current executing action (method) as an argument to the handler interceptors (pre/post handler actions)

[lmajano]

Pass in the current executing event to the handler interceptors (pre/post handler actions) as they also need to know what runnable event is being intercepted.

This is due in part that you can have a parent current event and then multiple chained events withing a request life cycle. By adding a second parameter to the interceptor methods. The interceptors can distinguish exceptions between the main event and just runnable events.
