Helper class for injecting and calling lifecycle callbacks unmanaged instances for use by framework and library integrators.

 Unmanaged<Foo> unmanagedFoo = new Unmanaged<Foo>(Foo.class);
 UnmanagedInstance<Foo> fooInstance = unmanagedFoo.newInstance();
 Foo foo = fooInstance.produce().inject().postConstruct().get();
 ... // Use the foo instance
 fooInstance.preDestroy().dispose();
 

An instance of this class can be safely held for the lifetime of the application.

Unmanaged.UnmanagedInstances created by this class are not suitable for sharing between threads.
