Dynamic assignment of a process class via parameter "scheduler.process_class" that points to a Universal Agent Cluster

Current Situation

• The order variable scheduler.remote_scheduler specifies the name of a remote JobScheduler instance in the form "host:port".

Desired Behavior

• It should be possible to assign a process class instead of a remote JobScheduler by use of the parameter scheduler.process_class
• This allows the same job chain to be executed for a number of Agent Clusters as the respective cluster is selected by the order, e.g. run the jobs from a job chain on hunderds of computers.
• Should process class assignments be used for a job, job chain or order then the following precedence is considered:
  • First precedence: process class configured by order parameter (this feature)
  • Next precedence: process class configured by job chain node (JS-1343)
  • Next precedence: process class configured by job chain (feature available wit JS-1301)
  • Last precedence: process class configured by job (feature available)

Maintainer Notes

• The currently used assignement is not valid for the JobScheduler Universal Agent that requires http or https as a protocol.
