These roles replace the jenkins-log-client portion of the
logstash/subunit queue processing system. Much of the code is
derived from the jenkins-log-client.
Rather than subscribing to ZMQ events emitted from jenkins (and
later zuul v2.5), these roles are intended to be run in a late base
post playbook (right after log uploading). They examine the logs
directory which contains the files that were just uploaded and any
matching files have jobs submitted to the gearman queue. Currently
the module attempts to maintain compatability as much as possible,
but eventually we should represent some of the data in a more v3-like
manner, as well as consider adding additional data. Some suggestions
are noted in comments.
