Implemented #371 (closed) as a flag in the run command where the user can supply the member or members allowed to run.
Added documentation.
Command example: autosubmit run a29z -rm 'fc0 fc3
The implementation includes validation.
The main logic is implemented inside a setter function for the run_members value of the JobList class.
We allow those jobs already submitted to continue to be tracked, even if they do not belong to the specified member.
