Bug Description

Eventlet workers should default to n-cpu not 1 for both main and admin APIs. The default of 1 with UUID tokens causes eventlet to perform extremely poorly under a default installation.

It is possible the minimum default should always be 2 workers. (Open for discussion)

    Add the processutils from oslo-incubator.

    This is a module specific add rather than a full sync. The processutils
    module will be used to determine the default number of workers for keystone
    running under eventlet.

    Processutils sync'd from oslo commit hash 6a60f84258

    Set the default number of workers when running under eventlet

    Keystone now defaults to n-cpu as the number of workers under eventlet with
    a minimum number of workers when auto-calculating the number of 2.

    This behavior can be overridded by changing the `admin_workers` and
    `public_workers` configuration values in the Keystone config file.
