Introduce a new endpoint to create policy

One first part of the update is to create a policy version from an existing one (this is similar as the create new policy).
The policy-flow.xml has been refactored so that the same policy query is done for policies and loop related flows. A code has been added to remove fields from the UI that could be present (the PDP group info json enrichment)
