[PR 1318][PR1318] introduces a monorepo member that's used as a DApp dependency, but the present arrangement whereby `test_dapps/` is an embedded monorepo makes it difficult to develop and test such packages in tandem with changes to `test_dapps/packages/*`. Reorganize `test_dapps/*` as members of the root monorepo and make various adjustments accordingly. This makes it easy to develop test dapps and any packages they depend on simultaneously, but we lose the CI/QA arrangement where test dapps are run with an embark installed from fresh tarballs. That arrangement, which is quite worthwhile as a means to detect problems arising from transitive dependencies as soon as possible, will be re-introduced in another PR, possibly involving an auxiliary repository such as embark-framework/dapp-bin. Since the `package.json` `"test"` scripts of `test_dapps/*` are now kicked off as part of `yarn test` in the root, and since port allocation isn't fully dynamic, it's important to run `yarn test` with `lerna run`'s `--concurrency=1` option. For the same reasons, the root `ci` and `qa` scripts are similarly restricted. In the future, this setup can be refactored and improved, along with use of `lerna run`'s `--since` option to increase testing efficiency in CI.
