What should we add?

The goal of this issue is to track the development of the client for the effective dimension runtime program (also under development), as described in epic https://github.com/Qiskit/qiskit-machine-learning/issues/318. The latest progress on this issue can be found in my personal fork: https://github.com/ElePT/qiskit-machine-learning/tree/eff-dim, under qiskit_machine_learnig/runtime

Although the title is given as Effective Dimension Runtime Program this will just add the Client here right - the server side Program being elsewhere.
