CI pipeline tool spike

[Anike Arni]

Due to the sunsetting of SnapCI, we now have to look elsewhere for a CI tool.

Acceptance Criteria

Have a assessment of benefits of each tool.

In Scope

Transfer our pipeline to alternative tools that fulfill at least the following:

• Integrate with Github
• Integrate with pull requests

Some tools we already discussed were:

• Travis
• CircleCI

Tulio & I spiked on CircleCI. We could complete the build with a circle.yml file with the following contents -

machine:
  python:
    version:
      2.7
  node:
    version:
      6.1.0
  environment:
    LC_ALL: 'en_US.UTF-8'

dependencies:
  override:
    - make clean_all
    - pip install -U --force-reinstall --no-cache-dir virtualenv
    - gem install compass && rbenv rehash

test:
  override:
    - make linters
    - make test
    - make functional_tests_ci

We looked at TravisCI features and it seems to be more or less the same as what CircleCI offers. So we don't see the need for doing a spike on that as well.
