[RFC]: Allow for stategy listener priority to be configurable

[visto9259]

RFC

Q	A
Proposed Version(s)	4.2.x
BC Break?	No

Goal

Priorities of strategy listeners are currently hard-coded.
Allow for priorities to be configurable with default values being set to the current hard-coded values.

Background

#172 provided a quick patch to fix priority issues for the UnAuthorizedStrategy that defaults to 1 which is the same priority as MVC's listeners to the MvcEvent::EVENT_DISPATCH_ERROR.

Considerations

• Modifying priority must be done after thoughtful consideration and a good understanding of how the MvcEven is handled in the application.
• Documentation is needed to explain the impact

Proposal(s)

• Add a prority option to listener configurations in lmc_rbac config for strategy listener
• Update documentation to explain how to change priority and potential impacts
