CLOUDP-280230: Refactor adds Project Dual Reference

[josvazg]

While the refactor change accept many files, there are only a few key places that are key:

• The new ProjectDualReference at pkg/api/v1/projectref.go encapsulates together the 3 fields that are required for all CRDs that depend on a project and have dual mode of operation with independent IDs and Kubernetes references.
• The credentials types at pkg/api/credentials.go are simplifies all types but CredentialsProvider interface disappear and a new ObjectwithCredentials allows indexers to define kubertenes objects that carry credentials, such is the case of these dual references.
• All CRDs supporting independent usage are changed to use the new ProjectDualReference.

All the rest of changes are derived from there:

• Some CRD descriptions are changes to become consistent under config/crd/bases. There are no changes to the YAML, this is a refactor.
• Some reference namings are corrected to be consistent across all types now.
• All tests need to be fixed with the new type shape, fields are moved around, and sometimes renamed.

This PR contains 5 commits, the new code infrastructure and 4 more for each type migrated to use it, db users, custom roles, private endpoints and deployments.
