Lower default heartbeat setting to 240 seconds

F5 load balancers by default will close TCP connections
that have been idle for 300 seconds.

The choice of the new 240 seconds interval is not
particularly scientific: any < 10 minutes interval
would work, given that heartbeats are sent at
roughly 1/2 the interval. As far as
performance overhead from heartbeats goes, 240
is about as good as 590.
