Packages to keep (for now) because of dependencies

Path	Reason
src/main/java/uk/ac/cam/cares/jps/base/config	IKeys, JPSConstants, AgentLocator are widely used
src/main/java/uk/ac/cam/cares/jps/base/discovery	Required by query, scenario, config, and the email-router
src/main/java/uk/ac/cam/cares/jps/base/http	query package depends on HTTP helpers
src/main/java/uk/ac/cam/cares/jps/base/scenario	Still used by the query module

When the dependent modules are refactored these packages can be revisited.
