Do some forking to support 5
Do some forking to support 5

move server app version detection to its own function to make a
variable out of it, and hardcode it to 5 for development testing. Work
through forked code path to not use same summary loglines when gauging
bandwidth usage, pop two fields when looking at new format for prods.

Fun fact: the old way of checking bandwidth actually returns hits that
failed because SUS requests are no longer server from cache. Go Apple!
