API calls creating a job support the optional field name starting with v4 of the API.
This allows the user to specify a job name to be used to identify jobs easily.
The user can now specify them by using the '-n' flag (see '--help' for more information) for these calls.
The status API call will now also show the job name if present, otherwise the old behaviour of showing the job id will be used.
Also made some formatting improvements (status API call / help text)
Some fields that are returned are renamed for the status API call. Also update those.
