batch-system: Introduce <slurm-api-batch-system> record type.

A <slurm-api-batch-system> record type allows us an easy way to group
and pass along parameters required by the slurm-api batch system.

* bin/ravanan: Import (ravanan batch-system).
(main): Create <slurm-api-batch-system> object for batch-system
argument. Do not pass #:slurm-api-endpoint and #:slurm-jwt arguments.
*
ravanan/command-line-tool.scm: Import (ravanan batch-system).
(command-line-tool-supported-requirements): Check for slurm-api batch
system using slurm-api-batch-system?.
(run-command-line-tool): Check for slurm-api batch system using
slurm-api-batch-system?. Do not accept #:slurm-api-endpoint and
#:slurm-jwt arguments.
* ravanan/workflow.scm: Import (ravanan batch-system).
(workflow-scheduler): Do not accept #:slurm-api-endpoint and
#:slurm-jwt arguments. Pass batch-system to job-state-status.
(run-workflow): Check for slurm-api batch system using
slurm-api-batch-system?. Do not accept #:slurm-api-endpoint and
#:slurm-jwt arguments.
