Bill Thiede 630f6ca61f Document environment variables usage.
Running 'go run dev/envvardoc/envvardoc.go' now shows:
'All environment variables are documented'

I also took the liberty of cleaning-up our mishmash of logic for handling
boolean environment variables, and cleaned up a couple other spots that didn't
seem right.

This change adds docmentation for all variables starting with (CAM|DEV|AWS).
This leaves some variables still undocumented.  If there are variables worth
documenting in the following list, maybe we should rename them to have a
CAM{LI} prefix for consistency's sake:
