    support other components using apache mod_wsgi

    Keystone is moving to use apache mod_wsgi instead of standalone
    eventlet daemon. Packstack should support deployment of keystone
    using this model. A new command line switch --keystone-service-name
    is added, and a new config parameter CONFIG_KEYSTONE_SERVICE_NAME
    is added. If this is set to 'httpd', keystone will be set up to use
    apache mod_wsgi, otherwise, it will be a standalone eventlet service.

    There is some common apache configuration that must be done by
    every module that uses apache. There is a new class in packstack
    called packstack::apache_common. Each component that uses apache
    must call "include packstack::apache_common". This ensures that
    a subsequent component manifest will not wipe out apache
    configuration created by a previous component manifest or the initial
    apache configuration created by prescript.pp.
