Scripts and files for running end-to-end platform testing for Hops

You should have the same name for all branches of chef cookbooks in this JIRA issue. I keep a human readable name, not the JIRA number, as it can be remembered. Like 'tf_serving'. This means the Berksfile for hopsworks-chef branch should have references to the same 'tf_serving' branch in tensorflow-chef, ndb-chef, kagent-chef, etc.

1. Fork hops-testing to your own repository.

2. git checkout -b JIRA-ID

3. git push -u origin JIRA-ID

4. Generate test_manifesto

./scripts/generate_test_manifesto.sh

This will generate a new commit for hopsworks-chef for your branch with the Berksfile references all set to 'master', making a backup with the old Berksfile, so you can rollback for running Vagrant again.

./scripts/generate_test_manifesto.sh rollback reverts the Berksfile master changes.

This will generate a new commit for hopsworks-chef for your branch with the Berksfile references all set back to '', so you can run Vagrant again.

Some tests don't need to run with every testing instance, as they take too much time to complete and the testing pipeline is slowed down. To run only these tests, in your hops-testing pull request you need to set the "it" => false property to "it" => true in both hops-testing/templates/Vagrantfile-centos and hops-testing/templates/Vagrantfile-ubuntu files.
