@StephanEwen @zentol , thanks for review this pr
yes, I had check the dependency.
by the way, in order to distinguish between different prometheus tasks, I
defined different jobname for each flink job, so it can collect the metrics of
separate project.
although pushgateway has some limits currently, it may be useful in some
cases, and pushgateway can be upgraded.---
