Add the ability for Zuul to accept inputs from multiple trigger sources simultaneously. Pipelines are associated with exactly one trigger, which must now be named in the configuration file. Co-Authored-By: Monty Taylor <mordred@inaugust.com> Change-Id: Ief2b31a7b8d85d30817f2747c1e2635f71ea24b9

Since 1.3.0:
- The Jenkins launcher is replaced with Gearman launcher. An internal Gearman server is provided, and there is a Gearman plugin for Jenkins, so migration to the new system should be fairly straightforward. See the Launchers section of the documentation for details.
- The custom parameter function signature has changed. It now takes a QueueItem as the first argument, rather than the Change. The QueueItem has the full context for why the change is being run (including the pipeline, items ahead and behind, etc.). The Change is still available via the "change" attribute on the QueueItem. The second argument is now the Job that is about to be run, and the parameter dictionary is shifted to the third position.
- The ZUUL_SHORT* parameters have been removed (the same functionality may be achieved with a custom parameter function that matches all jobs).
- Multiple triggers are now supported, in principle (though only Gerrit is defined currently). Your layout.yaml file will need to change to add the key "gerrit:" inside of the "triggers:" list to specify a Gerrit trigger (and facilitate adding other kinds of triggers later). See the sample layout.yaml.
- The default behavior is now to immediately dequeue changes that have merge conflicts, even those not at the head of the queue. To enable the old behavior (which would wait until the conflicting change was at the head before dequeuing it), see the new "dequeue-on-conflict" option.
- Some statsd keys have changed in a backwards incompatible way:
- The counters and timers of the form zuul.job.{name} is now split into several keys of the form: zuul.pipeline.{pipeline-name}.job.{job-name}.{result}
- Job names in statsd keys now have the '_' character substituted for the '.' character.
