fix role tests

Ansible role tests were failing due to ansible-lint reporting
multiple errors.

Fixing those errors resolves the failing tests.

Switching gcsfuse to use gcloud's bootstrap to follow the current
docker install instructions.

Removing centos as it's a discontinued distribution.

Adding a check to ensure integration tests are skipped unless they
are run by a branch (a public fork does not pass required
integration test credentials).
