Huge PR, where should we focus? ;)

@dbreese Unfortunately due to moving project files around and fixing lots of prettier & linting errors, it's impossible to keep this PR small. I guess to verify, just clone locally and check that yarn install && yarn precommit will run/pass the linting & prettier & tests.

For me everything passes locally but in CI for some reason 1 test is failing so I still need to look into that.

I see that only a subset of projects are configured to run tests. I'm presuming that's either because the others didn't have test targets, or their test targets don't work?

This looks fine to me in the broad details. In the future I'd recommend breaking this up into multiple PRs, to make it easier to review. Even though you're working on a lot of files, there are still ways to minimize the impact of reviewing those changes by breaking them up. For example:

• First PR simply moves all projects under the projects/ umbrella. No further changes.
• Second PR reformats all files with prettier. No further changes.
• (Optional) 3rd to n PRs do the same for any other applicable targets (lint, test, etc.).
• Final PR implements Lerna configuration changes to support the monorepo.

There were a number of changes aggregated in this PR, that would have been more easily reviewed by splitting them out.

Thanks for taking this on! It'll help manage all of the disparate projects a lot more consistently here. 👍

Yes some projects do not have tests. We can have follow up PRs to add tests to these sample LWC projects if we want to.
