Lots of code redundancy between Task and Debug managers

[colin-grant-work]

Feature Description:

The TaskConfigurationModel is basically the same as the DebugConfigurationModel and the TaskConfigurationManager is basically the same as the DebugConfigurationManager, except that @tsmaeder and I have done work on the tasks side to add support for User and Workspace scopes, while debug still only supports Folder scope. It's likely desirable to refactor to reuse as much the code as possible (maybe locate the refactor in the preferences package as a util, something like SectionConfigurationModel and SectionConfigurationManager), and if we do it right, we might get support for multiple scopes in the debug package for free.
