python client wrapper based on generator

[pcrespov]

When API exposes job pagination, I would like to have a compatible client function JobsAPI.list_jobs that includes pagination parameters (defaulted to compatible values) and an extra function that JobsAPi.iter_jobs to seamlessly iterate all jobs as with https://github.com/ITISFoundation/osparc-simcore/blob/master/packages/pytest-simcore/src/pytest_simcore/helpers/utils_docker_registry.py#LL48C5-L66C74

@pcrespov I consider this issue done, so I close it for the review, so it is clear the pagination has been implemented. I leave this comment in case you have further remarks/thought on what needs to happen. Please let me know
