closes #1394

I didn't see any specific tests for these files (but I'm happy to add them if they are just structured differently).

Hey @knechtionscoding, thanks for the contribution!
You need to update CRDs to make new attributes available in the components' specifications. We have a Python script to propagate these changes automatically, all you have to do is update hack/crd-update/crd-update.py:

diff --git a/hack/crd-update/crd-update.py b/hack/crd-update/crd-update.py
index 6f78d5a4..855dc14b 100755
--- a/hack/crd-update/crd-update.py
+++ b/hack/crd-update/crd-update.py
@@ -17,6 +17,11 @@ try:
           description: Kubernetes object parameters to apply on top of default adapter values.
           type: object
           properties:
+            annotations:

             labels:
               description: Adapter labels.
               type: object

then run ./hack/crd-update/update-all-crds.sh and commit all changes after the script finishes its job.

Regarding the tests. There is a totally outdated and inefficient TestAdapterOverrideOptions, and we need to make it relevant someday, meanwhile, the easy path is to add (Pod)Annotation objectOption in deployment_test.go and knservice_test.go to validate its effect on the adapter.

@tzununbekov I think I've got all of that done, let me know if there's anything left!

[tzununbekov]

Yes, perfect! I forgot about the codegen update, so I took care of it to get this PR merged today. Thanks!

Appreciate the help to get it over the finish line @tzununbekov !
