Continuous Integration Improvements

[keithligon]

Improve the continuous integration pipeline for the sprout-upgrade branch.

The current workflow only runs a limited set of tests. Next steps:

1. Separate tests runs into separate steps and sequence, stop on failure. Start with common unit tests, then client (to be added) and api unit tests in parallel, then api acceptance tests
2. Add liniting
3. Add coverage
4. Automate deployment to environment created in issue 28
5. Attempt merge on commit to master branch.

Tests are now separate steps and dependent on previous steps passing. Need to merge client updates.
