Interface: IVsTrackProjectRetargeting

The interface to TrackProjectRetargeting service. This is a  global service that
tracks project re-targeting attempts and broadcasts events to all subscribers 
related to various stages of the re-targeting operation. The normal situation is
to call with reloadProject set to true. If reloadProject is false, the expectation
is that the calling project is ready to deal with the new framework version 
without a reload.
