Introducing JMX custom tagging

The latest version of Datadog Agent, 5.1.0, introduces new options for tagging metrics collected by the JMX integration. Users can now assign custom tags to each metric, providing more descriptive and relevant information compared to default MBean developer-assigned tags. To use this feature, users need to upgrade to Datadog Agent 5.1.0 and follow the configuration instructions in the documentation. This enhancement was made possible by a pull request from customer Keen.io, highlighting the value of community contributions to software development.
