The dependencies should be specified at the deployment unit level
as when you create a service you know what dependencies you
have. This does not mean that the unit deployer has to handle the
dependencies. I don't want to have to edit a dependencies.xml in
a deploy directory and then drop my service jar into the deploy directory.
The deployment unit should be a self describing unit.
