Add docker compose test environment

[solocommand]

For those of us who may not have a readily available local test environment, this PR adds php5.6 test runner using Docker Compose.

To execute the standard test suite: docker-compose run test
To execute the end to end test suite: docker-compose run e2e

Example output:

$ docker-compose run e2e
> __exec_command: phpunit '-c' 'phpunit.e2e.xml' '-v'
