feat(cwl_reana): pass resource requests/limits to job-controller

Closes reanahub/reana#883

Shouldn't these be set automatically from the CWL ResourceRequirements.{cores,ram}Max?

As you probably know, due to the multi-workflow-engine nature of REANA, we have a job controller that exposes the same API for all workflow engines and handles the actual dispatching itself. We can certainly parse the parameter you mentioned in reana-workflow-engine-cwl and pass it to the REANA job controller. However, to stay compatible with our kubernetes_memory_limit implementation, we chose to implement it this way. You can refer to the kubernetes_memory_limit implementation here:
https://docs.reana.io/advanced-usage/compute-backends/kubernetes/#custom-memory-limit

Great, please let me know how I can help with that. The timeout option also duplicates a built-in CWL feature. https://www.commonwl.org/v1.2/CommandLineTool.html#ToolTimeLimit
