Support prometheus client 1.x

[pjfanning]

Please describe the feature request.

Prometheus Client 1.x releases differ from the 0.16 release.

Rationale

Use the v1 release instead of the v0 releases.

Additional context

• https://prometheus.github.io/client_java/
• the jars seem to have been renamed - eg https://github.com/prometheus/client_java/blob/main/examples/example-prometheus-properties/pom.xml
• io.prometheus:prometheus-metrics-core:1.1.0 seems to have the same package names as the io.prometheus:simpleclient jars have

This is related: #3987
Unfortunately this is not very easy since Prometheus Client 1.0 was released with a lot of breaking changes.

Any chance the v1 client might improve the situation with #877 ?

It's possible. We'll revisit that when we've figured out the details of the upgrade.

Fyi: we added initial support for this (see the PR description, TL;DR: exemplars and native histograms do not work yet): #4846.
It was released yesterday in 1.13.0-M2 please feel free to try it out and give us feedback.
