Continuous integration

[JohnStrunk]

Describe the feature you'd like to have. We need a CI system to ensure master remains healthy as development progresses.

What is the value to the end user? (why is it a priority?) Having a healthy master means that users don't need to search for a "stable build" to use, and we will be able to release new features faster with higher quality than would otherwise be possible.

How will we know we have a good solution? (acceptance criteria)

• CI system runs against all PRs and master branch
• CI system runs linters
• CI system runs all unit tests
• CI system runs e2e tests

Work items

• [ ] Unit testing: #31
  • TravisCI: linters, unit tests
  • codecov
• [ ] E2E testing via CentOS CI - #29
