The download retry interval was previously five seconds which is
not long enough to recover after a hard network connectivity break
where we may be reliant upon network port forwarding hold-down
timers or even routing protocol route propogation to recover
communication.
Previously the time value was 5 seconds, with 3 attempts, meaning
15 seconds total ignoring the error detection timeouts.
Now it is 10 seconds, with 10 attempts, meaning 100 seconds before
the error detection timeouts.
