This patch is adding the configuration of the number of workers,
threads, and the size of the listen queue in Debian, which uses
uwsgi to run Keystone. Therefore, this patch adds a new
keystone_uwsgi_config provider as well as a new keystone::wsgi::uwsgi
class.
This is, hopefully, the first of a long series of patches for
the whole puppet-openstack to add uwsgi support.
