On mirror.fuel-infra.org there is a package
td-agent-additional-plugins which ships all the additional
fluentd gems (plugins and its deps).

Its possible for fluentd to match and report false positives with
current regex for hdd errors. The following log example line:
failed to deactivate service binding for container
 jenkins_slave02.1.tijvdstzxrs6gikbwrtu85078" error=
can be catched by the regex and report about the (false positive)
issue will be sent to prometheus. So the new regex must be more strict,
in order to avoid such alerts.
