Hi @fscnick could you please tell me a bit about why we need to upgrade that library? It's not clear from your issue

[fscnick]

If prometheus client with v1.0.0 or higher version is used in a program and also some argo package has been included. That caused an compilation error because the higher version would be taken. However, it has different input arguments. Or there is other consideration.

Will consider this PR after merging #1853

@fscnick Seems like we're going to upgrade the client in #2097 along with Go 1.13. I'll be closing this for now, but thanks for submitting this PR.
