no issue
- Renovate merged in a breaking change to ember-cli-code-coverage which
broke our coverage reporting for the admin app
- This commit fixes the issue by pinning the version of
ember-cli-code-coverage to the last working version and telling renovate
to ignore it in the future
- It also adds html coverage reporting to make it easier to run locally
and see your coverage before pushing

- this commit:
- adds the `ember-cli-code-coverage` dependency to collect
coverage from ember tests
- enables the `COVERAGE` env variable in CI
- merges coverage data because tests are run in parallel
- adds the codecov GitHub Action into CI so we can upload
coverage reports
no issue
- improves test run times by splitting the tests into multiple groups and running each in their own browser instance
- settled on 2 browser instances as that seems to best fit within Travis' memory and CPU constraints
- updated ember-cli-code-coverage config to work with parallel builds
