A provider for ExecuteListener instances. 

In order to facilitate the lifecycle management of
ExecuteListener instances that are provided to a jOOQ Configuration, clients can implement this API. To jOOQ, it is thus irrelevant, if execute listeners are stateful or stateless, local to an execution, or global to an application.

Provide an ExecuteListener instance.

Implementations are free to choose whether this method returns new
