[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.
