Remove JAXB and XML, use GSON for JSON

This review converst apex-pdp to use GSON for JSON handling. In order to
preserve backward compatibility with the JAXB format of JSON, custom
handling of maps was required. Therefore, the policy-common
StandardCoder could not be used.

There are a lot of small changes, removing annotations from concepts and
tweaking of test data. However, this cleans up the code base so it is
worth doing.
