Also, moved is_first_master method into superclass for reuse. And look
at oo_first_master and ansible_host instead of masters and
ansible_ssh_host.

Some refactoring of checks and the action plugin to enable writing files
locally about the check operation and results, if the user wants them.
This is aimed at enabling persistent and machine-readable results from
recurring runs of health checks.
Now, rather than trying to build a result hash to return from running
each check, checks can just register what they need to as they're going
along, and the action plugin processes state when the check is done.
Checks can register failures, notes about what they saw, and arbitrary
files to be saved into a directory structure where the user specifies.
If no directory is specified, no files are written.
At this time checks can still return a result hash, but that will likely
be refactored away in the next iteration.
Multiple failures can be registered without halting check execution.
Throwing an exception or returning a hash with "failed" is registered as
a failure.
execute_module now does a little more with the results. Results are
automatically included in notes and written individually as files.
"changed" results are propagated. Some json results are decoded.
A few of the checks were enhanced to use these features; all get some of
the features for free.

Turn failure messages into exceptions that tests can look for without
depending on text meant for humans.
Turn logging_namespace property into a method.
Get rid of _exec_oc and just use logging.exec_oc.

Introduced the 'changed' property for checks that can make changes to
track whether they did or not. Rather than the check's own logic having
to track this and include it in the result hash, just set the property
and have the action plugin insert it in the result hash after running
(even if there is an exception).
Cleared out a lot of crufty "changed: false" hash entries.

Move task_vars into instance variable so we don't have to pass it
around everywhere. Also store tmp. Make sure both are filled in on
execute_module.
In the process, is_active became an instance method, and task_vars is
basically never used directly outside of test code.

It is a function/callable, the name should imply action, should be a
verb and not a noun.
Keep supporting the old name while we have PRs in-flight that use the
old name.

It turns out the code in
roles/openshift_health_checker/openshift_checks/__init__.py had a
mistake in the import statement, and not the case that `add_metaclass`
is not available in the embedded `six` from `ansible.module_utils`.
The fix is to correct the import and do not require python-six to be
installed on target hosts.
Note: now that we have some unit tests in the role, errors like that
would have been caught.

Embedded version of six in Ansible 2.2.1 does not support add_metaclass,
so revert to using python-six.

This allows us to refer to a group of checks using a single handle.

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.
