    Introduce a new lister_get endpoint

commit 2bf1109c21ac77b7f03ad993f4cf0650390b929b
Author: Nicolas Dandrimont <nicolas@dandrimont.eu>
Date:   Tue Jan 19 14:23:32 2021 +0100

    Implement some basic aggregated metrics on listed origins
    
    Metrics are computed and cached database-side by the `update_metrics`
    function. The `get_metrics` function only retrieves the cached data.

Author: Valentin Lorentz <vlorentz@softwareheritage.org>
Date:   Tue Jan 19 18:36:53 2021 +0100

    simulator: stop using get_scheduler directly
    
    This reuses the scheduler instantiated by the cli instead of hardcoding
    our own using the PG* variables.

commit 5bee207dca74bb2c70611b3308c93bc522d48247
Author: Nicolas Dandrimont <nicolas@dandrimont.eu>
Date:   Fri Jan 15 16:33:43 2021 +0100

    simulator: implement a simulator for the "old" task-based scheduler
    
    We extend the Task object with an autogenerated uuid allowing us to
    track the task lifetime between its creation and the generation of visit
    statuses, as the task-based scheduler does.

    For now, this collects the runtime of tasks that have run, and gets
    printed at the end of the simulation.

    simulator: refine origin model to follow an exponential distribution
    
    This models origins using a consistent characteristic "time between
    commits" that follows an exponential distribution between 1 second and
    10 years.
    
    From this characteristic time, and feedback from the OriginVisitStats,
    we can generate the expected run time and output status of the next
    visit of that origin.

    simulator: simulate the scheduler journal client

commit c9b0728955e683748f8b03a22f91d501b64aad67
Author: Valentin Lorentz <vlorentz@softwareheritage.org>
Date:   Thu Jan 14 15:12:38 2021 +0100

    simulator: generate OriginVisitStatus objects in modeled visits
    
    To be able to generate uneventful visits, we would need to store
    the last snapshot seen for a given origin. Instead of storing this
    within the simulator, which would be a concern for large scale
    simulations, we use the scheduler visit cache directly.

Author: Valentin Lorentz <vlorentz@softwareheritage.org>
Date:   Thu Jan 14 15:09:58 2021 +0100

    simulator: Move scheduler into the simulation environment object
    
    The scheduler is used by a lot of the simulated actors, it makes sense
    to share it all the time.

    simulator: Use datetimes instead of a floating point simulated time

commit ef241dd84c400f9be0d92396867587d47216e385

Date:   Wed Jan 13 16:13:01 2021 +0100

    Introduce scaffolding for a scheduler simulator
    
    This simulator will allow us to compare the behavior of the old and new
    schedulers, as well as to test the impact of scheduler policies and their
    parameters on the performance of the Software Heritage archival
    infrastructure as a whole.

    Import the journal subcommand in the main swh.scheduler cli
    
    This issue was masked by tox.ini using pytest with --doctest-modules,
    which imports all modules during test collection, and therefore executing
    the side-effects of swh.scheduler.cli.journal.

See https://jenkins.softwareheritage.org/job/DSCH/job/tests-on-diff/174/ for more details.

commit 114ed952e513c7ad3dbb038a640e80bf079d0780
Author: Nicolas Dandrimont <nicolas@dandrimont.eu>
Date:   Tue Jan 19 14:23:32 2021 +0100

    Implement some basic aggregated metrics on listed origins
    
    Metrics are computed and cached database-side by the `update_metrics`
    function. The `get_metrics` function only retrieves the cached data.
    
    The metrics are aggregated for each lister instance and visit type
    (allowing complete reaggregation by visit type for cross-cutting statistics).
    
    The following metrics have been implemented:
     - number of known origins overall
     - number of enabled origins (origins seen in the last listing)
     - number of enabled origins that have never been successfully visited
     - number of enabled origins with known activity since our last successful visit
