improvements to coupled start scripts

[orichters]

Purpose of this PR

• saving some improvements introduced in add multiplayer mode for coupled runs #1335
• shift coupled model tests to auto mode to avoid that they fail on lack of priority runs
• In case of fail tell user which command line arguments were passed to start_bundle_coupled.R
• provide qos statistics after running start_bundle_coupled.R
• ask before deleting any folder, and never delete on gamscompile
• put plot_compare_iterations behind "try" such that it finishes the rest of the script in case of failure there
• put Costs Without Incentives (million US$05/yr) as introduced here behind if to not fail on old reporting…
• Use --mem=8000 option only if running on 1 CPU. I asked in the RSE channel a while ago whether adding it would harm, and it does:

slurmstepd: error: Job 26812886 exceeded memory limit (8344256 > 8192000), being killed
slurmstepd: error: Exceeded job memory limit
slurmstepd: error: *** JOB 26812886 ON cs-f14c02b10 CANCELLED AT 2023-06-16T00:37:19 ***

Type of change

• Bug fix (mem=, plot_compare_iterations)
• Refactoring

• All automated model tests pass (FAIL 0 in the output of make test-coupled). See /p/tmp/oliverr/remind-smallfix/slurm-26964374.out
