This commit does not belong to any branch on this repository, and may belong to a fork outside of the repository.
- This PR implements the upstream proposal at: crossplane/crossplane#3939 - Subpackages belonging to each API group is produced. An example is: provider-gcp-cloudplatform. - ProviderConfig, ProviderConfigUsage and StoreConfig are part of a config package named provider-gcp-config. - The monolith package (containing all the CRDs and associated controllers) is still produced. - Each produced package except for the monolith package has the `pkg.crossplane.io/provider-family` label in its package metadata. - Each service package except for the config package declares a dependency to the config package.
