// wu_is_infeasible_custom()
// Decide whether host can run a job using a particular app version.
// In addition it can:
// - set the app version's resource usage and/or FLOPS rate estimate
// (by assigning to bav.host_usage)
// - modify command-line args
// (by assigning to bav.host_usage.cmdline)
// - set the job's FLOPS count
// (by assigning to wu.rsc_fpops_est)
//
// app_plan()
// Decide whether host can use an app version,
// and if so what resources it will use
//
// app_plan_uses_gpu():
// Which plan classes use GPUs
//
// JOB::get_score():
// Determine the value of sending a particular job to host;
// (used only by "matchmaker" scheduling)
