New CMS pipeline mechanism

Pipelines deployed by the CMS now get data through the same PEP (vs directly accessing the data in the DB and filtering it inside the pipeline).

Workflow:

1. The filters makes a query to the PEP with its certificate
2. The PEP verifies the certificate
3. The PEP verifies with the PDP what data the filter can access
4. If PDP approved, the PEP sends the required data to the filter
5. The filter passes the data to the algorithm, and so on...
