ansible-lint was updated and the GitHub
action did not pin the dependency, resulting
in the repository to fail sanity tests.
Updating the repository to adhere to new fatal
linter rules, but also pinning the linter to
prevent failures that may be unrelated to the
particular commit.
Updating usages for python3.8 to 3.9 as ansible-lint
is dropping support for 3.8.
Ansible-lint is required for Ansible collection
certification for Automation Hub.
gcsfuse had no metadata associated with it, failing
the Ansible Hub upload.
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).
