What would you like to be added:
Currently, the status.secretRef field in the AccessRequest resource is of type common.ObjectReference, which consists of name and namespace.
Unless we can think of a scenario where the ClusterProvider needs to put the AccessRequest's secret in a different namespace than the one the AccessRequest is in, we should remove the namespace field.
The AccessRequest currently has no fields to influence the metadata of the generated secret in any way
Why is this needed:
Cleans up and simplifies coding by removing an unnecessary field.
