Required changes to deployment layer

This is the umbrella task for the following

#1 Allign deployment phases with bundle lifecyle. It should be possible for DUPs to operate on resolved bundles that have an associated Module

#2 Add start/stop lifecycle for deployments. Bundles as well as JSR88 deployments have the notion of start/stop

#3 Allow DUPs to operate on a set of deployments. It should be possible to deploy a set of bundles in arbitrary order. When all deployments in the set are installed - they can be resolved/started.

#4 Allow the management client to associate metadata with a deployment that can be seen by the DUPs. This is needed to be able to specify autostart behavior and a potential start level.
