The Microservice CRD is responsible for defining what components make a Microservice.
The Microservice controller is responsible for creating a set of VersionedMicroservices. These VersionedMicroservices depend on available releases, which are defined by the ImagePolicy and ConfigPolicy.
For each new Release or Configuration, the Microservice will create a new VersionedMicroservice and annotate it appropriately. These annotations are important so we can use them in other parts of the system.
The Microservice Controller also takes care of deleting deprecated versions from the system. It does this by looking at which releases should be deployed and which ones are currently deployed. If there are versions available that shouldn't be released anymore, it will delete them.
