We should also review our current deployment process before merge this as it affects how we are doing the releases.

Should we use the version to have control over what qiskit-serverless we are installing?

Yes, I was thinking to do something similar as we are already doing with DYNAMIC_DEPENDENCIES_FILE. But then I realize what will be the point to not use the latest version published. Right now, we are using the latest version not published yet.

Summary
The K8s deployment generates the images from all the services (gateway, scheduler and Ray base image of functions). When the Ray image is generated, it installs Qiskit Serverless from the
clientfolder. This means that every time we deploy the services, the latest version of the client in main branch is used, which may include unfinished changes.This PR changes how the Ray base image for functions is generated. Instead of copying the client, it just installs it from pip. This will allow deploying the services at any time without worrying about the client state.
