Update phoenix to v0.17.0 (latest), fix config, make tests pass

[thousandsofthem]

• phoenix version 0.17.0 now (latest ). was 0.13.0
• Regenerated the phoenix app from scratch using all-default built-in generator (mix phoenix.new)
• Tuned config to match other apps (pool size i.e.)
• Now all tests passing without warnings
• Updated elixir 1.0.4 -> 1.0.5
• Includes Clean up code and update Elixir #1729

"Round 11 Preview" numbers are off by factor of ~ten. Primary reason: Wrong pool size (way too low)

ugh ugh.
There are more recent update present (recently opened and already merged), phoenix 1.0.3 - #1751
This one is outdated - phoenix v0.17.0

@blee-techempower could you please revert merge?

@thousandsofthem I'm not sure why GH thinks that this is merged; I just checked master and it is not. You should double-check to make sure, but I think that we are okay on this and GitHub is just being a little weird.

¯_(ツ)_/¯
