Deployment descriptor per deployment

We should have some sort of deployment descriptors and the deployment service would make the plumbing based on that descriptor. So with that descriptor we could configure following:

• class loading, what besides the normal dependencies defined should be added to class loader of the project
• what persistence unit it shall use
• shall it use persistence at all (something that Jeff mentioned on early access list)
• logger - JPA, JMS, none
• strategy (singleton, per process instance, per request)
• work item handler configuration (and other session configurations)
• interceptors?
• might be more

Such a descriptor could be added:

• to the kjar
• related to a deployment (system repo?)
• as default (where the defaults should be configurable themselves as well)
