upgrade:

|
||||
WSGI application script ``masakari-wsgi`` is now available. It allows
|
||||
running the masakari APIs using a WSGI server of choice (for example
|
||||
nginx and uwsgi, apache2 with mod_proxy_uwsgi or gunicorn).
|
||||
The eventlet-based servers are still available, but the WSGI options will
|
||||
allow greater deployment flexibility.
