Dev: Workflow event types

[Corwinpro]

This PR extends the changes introduced in #269 This PR approaches #247, and #333 of the WorkflowManager

Summary

We introduce mco_events types to the BaseMCOModel class. Now developers are able to specify custom start, progress, and finish events in the MCOModel: events of these types will be raised at runtime.

notify_new_point is not deprecated. Use notify_progress_event instead.

Done

• Added _start_event_type, _progress_event_type and _finish_event_type to the BaseMCOModel:

  #: Type of the MCO Start event
  _start_event_type = Type(MCOStartEvent, visible=False, transient=True)

• Refactored the create_event methods of the BaseMCOModel: not these are called notify_*_event and immediately call self.notify method with an appropriate event.
• API update: notify_progress_event now accepts **kwargs as the third parameter, instead of weights. This allows users and developers to propagate custom data to the MCOProgessEvents.
• notify_new_point is now deprecated.
