handle job desribed by a CWL Workflow

Related to: https://gitlab.cta-observatory.org/cta-computing/dpps/dpps-project-management/dpps-use-cases/-/issues/54

For now only CommandLineTool are handle to treat input and output data in DIRAC.

How to treat Workflow?

• : use cwl_utils.pack to pack WF and CLT and use it as InputSandbox
• : extract from the input the additional input sandbox and/or data (should be the same as for CLT).
• : extract from the Workflow outputs, the outputs sandbox and/or data, by interpreting each steps.
• : handle JSRequirements -> nodejs needs to be a CTADIRAC dependency since the client will evaluate JS expression
• : handle StepInputExpressionRequirement
• : handle ExpressionTool + ScatterRequirement
• : write the documentation
