> With FLINK-3660, we added a metric that measures the latency of records flowing through
the system.
> With this JIRA, I would like to expose the latency also in the web frontend.
> Therefore, we'll probably need to change the format the latency is reported in the metric.
> I think we should show the latencies in two different views in the interface:
> - A global end-to-end latency in the overview of running jobs. This number is probably
pretty inaccurate, but should give users a first impression of the latency characteristics
currently present in the job
> - A detailed latency drill-down view, that allows to see how much latency is added on
average at each operator, for the sources.
