Description

We found that the native PushGateway does not support authentication. As a result, the metrics data in on YARN mode cannot be reported to pushGateway with authentication.  

Although we have some other solutions, such as landing files and others, we think pushGateway is the best solution.  

So I decided to do some implementation on my own, and will submit pr to the community later.

At present I only submit pr to the branch of Flink-1.13. If necessary, I think I can submit it to the master branch.
