Added FinalPath implementation

[Dr15Jones]

PR description:

OutputModules placed on a FinalPath do not cause unscheduled execution. This ability was requested by HLT.

As part of work, consolidated all copied code used in various OutputModuleBase implementations into one class.

PR validation:

Code compiles. All framework related unit tests (included the newly added ones) pass.
