Automate streamflow run process

Action items:

• create a project in rke2-1-dev-cineca for @vgeo
• @vgeo should familiarize with https://github.com/alpha-unito/streamflow , specifically https://github.com/alpha-unito/streamflow/tree/master/docs/source/cwl and all streamflow/cwl related material found in repo
• @vgeo hands-on/ test https://gitlab.ebrains.eu/ri/tech-hub/platform/workflows/streamflow-examples on k8s
• convert CWL workflow (<- this is what we ask from EBRAINS users) into streamflow.yml format (<- this is what steramflow expects) to run via streamflow in k8s
• use data-proxy for fetching the "input" files
• use data-proxy for uploading "output" files in object storage

Prior steps made by Nikos and Michalis:

• Although we have successfully tested StreamFlow Workflow Manager in streamflow-examples there is a need to automate the process of running CWL with streamflow like it is done by CWL-tes tool.
• For that purpose the streamflow-client repository has been created.
