My immediate motivation is that I'm going to try turning on the
pipelining setting, to improve performance, and I'd like to have the
consistent place to put it! But also, I like standardizing our setup a
bit more, too
I did some refactoring while here too, of pulling the deploy scripts out of `package.json` and into `bin`, to be a bit more canonically Rails-y. (idk how canonical the colon thing is but, probably fine??)
