Describe the feature

currently all the controller tests are based on a docker compose network with two connectors, that need to be built on every change, this makes testing slow and painful.
With the introduction of prism (see #215) we could switch all the tests to that approach (as we did on the EDC java client).
A single E2E test could be kept to verify the whole process with 2 "real" connectors

If applicable, add text / mockups / screenshots to help present your vision of the feature
