    Projects will need to update DB and recompile all back-end programs.

    Summary:
    - new way of computing credit
    - "reliable host" mechanism is per app version
    - "host punishment" mechanism is per app version
    - adjustment of wu.rsc_fpops_est provides the
        equivalent of per app version DCF
    - max jobs in progress is now per app
    - max jobs per RPC is now per app

    TODO:
    - reliable mechanism:
        - populate and use host_app_version.error_rate
        - populate host_app_version.turnaround
    - host punishment:
        - populate host_app_version.max_jobs_per_day
        - populate host_app_version.n_jobs_today
        - use app.max_jobs_per_day_init
    - job limits:
        - use app.max_jobs_in_progress, max_gpu_jobs_in_progress
        - use app.max_jobs_per_rpc
    - adjust wu.rsc_fpops_est
    - remove old credit stuff
        fpops_cumulative, credit_multiplier
        credit computation in scheduler
