## Summary of Changes
- Introduced a new annotation for processors, reporting tasks, controller
services - @RequiresInstanceClassLoading
- Added new builder method to PropertyDescriptor
dynamicallyModifiesClasspath(boolean)
- Created a new InstanceClassLoader that maintains a child-first internal
ClassLoader where classpath resources can be set, only used when component has
@RequiresInstanceClassLoading
- Added support to ExtensionManager to obtain ClassLoaders based on type +
id, before we only had by type
- If the type being requested supports instance class loading (the
annotation described above) it will create an InstanceClassLoader which starts
as a copy of the NAR ClassLoader for that type
- When properties are set on a component, the framework will identify the
properties that are classpath modifiers and add those resources to the
InstanceClassLoader's child resources
