Add Executor Merger and Ansible execution statsd counters
This adds the following counters:
- zuul.executor.*.phase.setup.<result> (setup task)
- zuul.executor.*.phase.reset.<result> (reset connection task)
- zuul.executor.*.phase.<phase>.<result> (pre/run/post playbooks)
- zuul.executor.*.merger.['SUCCESS','FAILURE'] (merger status)
The data provided by these counters are not very reliable in the sense
that the failures may not be related to the executor itself and is
instead a legitimate issue with the patch or the job it is running.
However, when averaged out, these counters should help us identify if
a particular executor is exhibiting irregular behavior when compared
to regular patterns or other executors.
