    [SUREFIRE-1679] Prevent classpath caching from causing pollution
    
    Previously, classpath caching was performed statically. This resulted
    in the classpath cached by one project for a particular provider
    being used by a subsequent project. As a result any customizations to
    the classpath, such as removing duplicate artifacts, would leak out
    and pollute the classpath used by subsequent projects.
    
    This commit prevents the pollution by making the classpath cache
    instance-scoped so that the cache is only used by a single mojo and,
    therefore, a single project.
