    Set connection timeout in container sync

    Container sync might get stuck without a connection timeout if the remote proxy
    is not responding.

    This patch sets a default timeout of 5.0 seconds for the connection attempt. The
    value is much higher than other connection timeouts inside Swift (0.5); however
    there might be a much higher latency to the remote peer, thus playing it safe.
    There is also a retry if the attempt timed out.

    Note that this setting only applies to the connection request itself. Setting
    this timeout does not apply when the remote proxy goes away during a request.

    Also added a short test to ensure urlopen is called with the timeout value.
