Increase Min/Max cloud run instances

        Recently, the Min/Max cloud run instances had been reduced in
        an attempt to fix the failure causing the stale apps.yml data.
        This commit increases the min instances to 1 for dev and 2 for
        staging and prod.  The max is set to 3 for all 3 environments.

        This also adjusts the gunicorn async workers to 3 which is based
        on the fact, instances for all environments are set to 1vCpu.
        Where n = vCpus, we get 2n + 1 as a basis for setting the
        workers.  This can be adjust in the future if we ever change the
        number of vCpus per instance.

        Other things:
        * Remove some unused ENVs
        * Remove max-requests and max-requests-jitter
