* Replace multi-role checks with action pluginRodolfo Carvalho2017-02-102-7/+0
| | | | | | | | | | | | | | | | | | This approach should make it easier to add new checks without having to write lots of YAML and doing things against Ansible (e.g. ignore_errors). A single action plugin determines what checks to run per each host, including arguments to the check. A check is implemented as a class with a run method, with the same signature as an action plugin and module, and is normally backed by a regular Ansible module. Each check is implemented as a separate Python file. This allows whoever adds a new check to focus solely in a single Python module, and potentially an Ansible module within library/ too. All checks are automatically loaded, and only active checks that are requested by the playbook get executed.
* Rename subrole facts -> initRodolfo Carvalho2017-01-132-0/+7
Trying to improve the name, `init` needs to be loaded before calling other subroles. We don't make `init` a dependency of `common`, `masters` and `nodes` to avoid running the relatively slow `openshift_facts` multiple times.
