Custom namespace results in excessive logs to kubeapi

[deefdragon]

What version of redis operator are you using?
redis-operator version: 0.18

Does this issue reproduce with the latest release?
yes

What operating system and processor architecture are you using (kubectl version)?

Client Version: v1.28.9
Kustomize Version: v5.0.4-0.20230601165947-6ce0bf390ce3
Server Version: v1.31.1

What did you do?
Deployed the operator to a namespace other than redis-operator (such as op-redis). Thus resulted in the api-server being unable to hit my webhook service. During my testing, I had to use the full domain name to get an IP address, and as I also have a custom cluster domain, this should be taken into consideration.

Someone in #955 had similar errors, and suggested editing the CRDs to remove certain conversion sections. Editing the CRDs is obviously not ideal.

What did you expect to see?
Normal operation of kube-apiserver such that there are no extraneous error logs.

What did you see instead?
Excess logs in the kube-apiserver logs about ListAndWatch errors. The following outputs approximatly once a second.

In your case it is HTTP 404 because it tries to connect to the webhook service in redis-operator, no matter where you install the operator, but in #955 it is installed in redis-operator namespace and gives 502 for some other reason.
