Increase connection timeout to 600 seconds, which should always be higher than

the connect() timeout, so that we'll use that rather than our own timeout by
defualt.  There timeout was set low for Big Red, but causes problems for very
large clusters, as there's no way to wire them up in 10 seconds most of the
time.
