SAR/ServiceController should be a facade over the generic dependency controller

Rework the ServiceCreator, ServiceConfigurator, ServiceController
to use the generic deployment controller.

This will allow MBeans to take part in the same dependency/injection protocol
as the plain javabeans provided by the MicroContainer.
It also adds the "Describe" stage to the lifecycle allowing classloading dependencies.

This will first be prototyped in system2 rather than system.

The initial work will not include reworking the XML to use JBossXB
schema binding, but that is obviously desirable.
