Currently there is no way to pass some metadata through the deployment API such that they could show up with the DU.
As a client I'd like to say autostart=false and in my DUP I'd like to pick that up and not start a deployment (i.e. a bundle) automatically
Generally it should be possible for the client to set some properties for the deployment in a generic way such that they get associated with the DeploymentUnit
For an OSGi deployment it would be necessary to be able to define that start behaviour and the start level.
