Cypress IO end to end tests

Fixes https://github.com/Lullabot/drupal9ci/issues/67

Work in progress. Added base files and jobs for all platforms. Nothing tested yet, just wanted to upload progress with the implementation that I had in mind.

@juampynr - this is now ready for review.

TravisCI took me a bit longer mostly because I wanted to simplify the docker-compose architecture to be in line with all the others. It now uses your docker images to build the docker containers and test behat and cypress.

All four platforms had successful CI passes and are linked at the top of this PR for reference.

Posted a few comments but this is already a huge step forward so I am merging it @fjgarlin.

THANK YOU!

You're welcome, it's been fun to bring Cypress into the combo. This whole project is really cool!
