- because of how the npm scripts were set up, we were running the full
Admin integration tests during the unit tests phase of CI
- this commit renames the majority of `test` to `test:unit` in the
package.json files, and aliases `test` to `test:unit`
- special packages like Admin have no-op'd `test:unit` scripts so we
don't end up running its tests

- the original project had a commit which fixes a specific test for
missing host headers
- funnily enough, this was our only missing coverage on this package, so
we achieve 100% with this
- we shouldn't need individual LICENSE files because these packages
won't be published, so the top-level one applies
- also cleaned up README files to remove mentions of Lerna monorepos and
install instructions
