Support io.micrometer.prometheusmetrics.PrometheusMeterRegistry

[karesti]

Description

Since Micrometer version 1.13.0 - Quarkus is in version 1.14.5 - io.micrometer.prometheus.PrometheusMeterRegistry is deprecated in favor of io.micrometer.prometheusmetrics.PrometheusMeterRegistry that lives in the micrometer-registry-prometheus dependency.

Since Infinispan 15.1, for example, we are using the new registry. However Quarkus does not still support the new registry in native mode. Infinispan 16.0 (next LTS) will be ready at the end of 2025

Tasks

• Move current quarkus-micrometer-registry-prometheus, the one using the legacy client, to Quarkiverse
• Update current extension to use the new prometheus v1.x client
• Documents changes and impacts

The plan for this is to move the current prometheus registry to Quarkiverse as a legacy v0.x prometheus client compliant.
The new Client v1.x will be implemented in core and will imply a breaking change.

Message format changes needs to be documented and potential impacts on the dashboards, in particular, the Grafana - LGTM Dev Service.
