Is your feature request related to a problem? Please describe.
Currently, when deploying an ArgoCD cluster via operator, it defaults to the name "in-cluster" and runs under the server https://kubernetes.default.svc. There seems to be no direct option to rename this default cluster during initial setup.

Describe the solution you'd like
Enable setting a custom name for the "in-cluster" directly in the ArgoCD custom resource during deployment.

Describe alternatives you've considered
The cluster name can be changed post-deployment via the UI or by updating the secret directly.
