Update `application-name` and `service-name` `management.wavefront`
properties to align with Spring Boot 2.x support. The properties now
use the wavefront terminology where `application` refers to an a
collection of (micro)`services`.
This commit also adds `cluster-name` and `shard-name` properties that
can be used to add additional items to the `ApplicationTags`.
