Process: allow the processor to know the process_id

[francescoingv]

Is your feature request related to a problem? Please describe. There are use cases where the process may benefit from knowing the processed job_id. E.g.: a specific ProcessManager may want to read the output files from the process: the process would then write job specific files in the job_id directory.

Describe the solution you'd like The setting should happen before the call to process.execute().

One solution would be the BaseManager try to set the processor.job_id, but do nothing if it fails.

BaseManager.execute_process()
        processor = self.get_processor(process_id)
+        try:
+           # if the processor can set the job id, do it.
+            processor.set_job_id(job_id)
+        except AttributeError:
+            pass

Even better: the BaseProcessor defines a method set_job_id() that does nothing. The method is available for derived classes, where needed.

BaseManager.execute_process()
        processor = self.get_processor(process_id)
+          processor.set_job_id(job_id)

BaseProcessor
+    def set_job_id(self, job_id: str) -> None:
+        """
+        set the job_id within the processor
+        To be implemented by derived classes where required.
+        """
+        pass

Describe alternatives you've considered A derived BaseManager class implementing the solution should modify the BaseManager.execute_process(). Given the minimal change, also not affecting any in place code, I would prefer to have the solution included in the release.

Additional context If approved I would like to submit a PR with the second solution.
