Add scala-steward to project

[zakpatterson]

Scala Steward automatically submits PRs for upgrading dependencies.

Example PR by scala steward:
typelevel/cats#2660

Many typelevel projects use it:
https://github.com/fthomas/scala-steward/blob/master/repos.md

Agree? I'll submit PR to scala steward.

Nice, looks great, I will have to use it in some other projects

scala-steward-org/scala-steward#219

[zakpatterson]

PR was merged, will have to see if PRs start coming in

I suspect initially it will just be bad because of tsec, but that should clear up. Our current dependencyUpdates backlog is:

Oof, the steward is going nuts!

[zakpatterson]

Yeah once we're up to speed it should be quieter, plus having an open PR for each upstream update that we're in conflict with is great.

Each time we merge any PR tho, N travis builds will start up for each individual outstanding steward PR.

Since you've merged a few, and we've seen the steward go ahead and update it's unmerged PRs, I'll close this.
