Policy: generate boilerplate policy type and constant code.

This is the first step to being able to re-constitute policy from a non-generic protobuf in a policy request in a fully automated way (i.e. the code for the process can be generated). The non-generic protobuf is required for automatic merging of policy on the server-side.
