3.0.0-M3 Actuator Metrics Export Properties

[fabapp2]

labels: ["good first issue","upgrade:boot-recipe","3.0.0"]

From the Release Notes:

We have moved the properties controlling the actuator metrics export. The old schema was management.metrics.export.<product>, the new one is management.<product>.metrics.export (Example: the prometheus properties moved from management.metrics.export.prometheus to management.prometheus.metrics.export). If you are using the spring-boot-properties-migrator, you will get notified at startup. See #30381 for details.

What needs to be done

• Find properties using the old schema
• Change the format following the new schema
• Overwrite the old property with the new

This should be done as (integrated) declarative plain OpenRewrite recipe
