Refactor so ccloud environment name is based on the variant

[rspurgeon]

Right now the ccloud environment name is kafka-devops, and this affects the configurations as they are linked by name. For example the microservices apps link to their bootstrap url by way of a named configuration that includes the environment name. However, if we want the dev variant environment name to be kafka-devops-dev, we'd have to update all the configuration names.

Investigate how to link application configuration names without this environment name link or by automating the linkage.
