[CECO-2029][DatadogAgentInternal] Setup dependencies with real owner while using copy for naming

[tbavelier]

What does this PR do?

• Provides a store option to use a different object than the owner to get labels/annotations, while still setting ownerref to the provided owner
• Uses this option solely in the DDAI controller to use the profile DDAI copy (that's using the DDA name) for labels/annotations while still setting the ownerref to an existing/real object

Motivation

• Avoid creating dependencies with non-existing object in ownerref causing it to be GCd: this would happen when using profiles and DDAI
