    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.

    Add a parameter to take advantage of the new(ish) eventlet socket timeout
    behaviour. Allows closing idle client connections after a period of
    time, eg:

    $ time nc localhost 8776
    real 1m0.063s

    Setting 'client_socket_timeout = 0' means do not timeout.

    DocImpact:
    Added wsgi_keep_alive option (default=True).
    Added client_socket_timeout option (default=900).

    SecurityImpact
