This commit continues moving plugins into lib_utils.

This commit does not move any plugins for add-on roles
such as logging and metrics.

This commit removes become:no statements that break
the installer in various ways.

This commit relocates filter_plugings to lib_utils,
changes the namespacing to prevent unintended use of
older versions that may be present in filter_plugins/
directory on existing installs.

Add lib_utils to meta depends for roles

Also consolidate some plugins into lib_utils from
various other areas.

Update rpm spec, obsolete plugin rpms.

Certificates with large serial numbers (such as those from commercial
vendors) previously failed to parse due to absent logic in the
FakeOpenSSLCertificate parser. This would cause the module to abort
and break any other roles depending on the cert expiry checking
results.

* Identifies large serials in HEX format for decimal conversion
* Update unit tests to parse a large serial

We are moving toward having adhoc post-install checks and so the
"preflight" designation needs to be widened.
Updated location to playbooks/byo/openshift-checks, added health check playbook, and updated README.
Also included the certificate_expiry playbooks.
Left behind symlinks and wrappers for existing checks.

To conform with the direction of the rest of the repo, the
openshift-checks playbooks are split into two directories, one under
playbooks/common with the actual invocation and one under
playbooks/byo for entrypoints that are just wrappers for the ones in common.

Because the certificate_expiry playbooks are intended not just to be
functional but to be examples that users modify, I did not split them
similarly. That could happen later after discussion but for now I just
left them whole under byo/openshift-checks/certificate_expiry.

In a project where contributors are free to use whatever editor they
want and we have linting tools that verify the proper formatting of
Python files, it should not be required to have a vim-specific line in
Python files.
