Micrometer's Dynatrace group property cannot be configured via application properties

[diepet]

From Micrometer 1.2.0 the following property has been added in order to set the Dynatrace process group name of where the metrics will be published:

management.metrics.export.dynatrace.group=mycustomgroup

I added the above property in an application.properties file of a simple Spring Boot 2 app, but it is completely unused.

Spring Boot 2 version used 2.2.2.RELEASE.

More details about that property are in the following Micrometer issue:
