    Adjust default Keystone httpd processes and threads

    This patch sets the Apache threads and processes for Keystone to match
    the recommendations based on performance testing done by the Keystone
    core team.

    This resolves an issue where the cryptography library will not allow
    multiple threads to register the osrandom engine.

    To compensate for the reduction in threads, the number of processes has
    been increased. Both the values remain tunable to suit a deployers needs.
