    Eventlet green threads not released back to pool

    Presently, the wsgi server allows persist connections hence even after the
    response is sent to the client, it doesn't close the client socket connection.
    Because of this problem, the green thread is not released back to the pool.

    In order to close the client socket connection explicitly after the
    response is sent and read successfully by the client, you simply have to
    set keepalive to False when you create a wsgi server.

    DocImpact:
    Added wsgi_keep_alive option (default=True).
    In order to maintain the backward compatibility, setting wsgi_keep_alive
    as True by default. Recommended is set it to False.

    This is port of Cinder change - [1]
