    hydra: bayfront: Tweak the configuration for builds.
    
    Make the Guix Build Coordinator agent more gentle, reducing the max
    parallel builds and decreasing the load average limit. Also reduce the
    default max-jobs at the daemon level (for builds happening not through
    the coordinator agent), and set the default cores to 24 to avoid one
    build from loading all the cores.
    
    * hydra/bayfront.scm (services)[guix-build-coordinator-agent-service-type]:
    Tweak max-parallel-builds and max-1min-load-average.
    [guix-service-type]: Tweak the extra-options.
