The Kubernetes authorization webhook previously lacked the ability to evaluate conditions on access requests, limiting fine-grained control as outlined in KEP 5681.

The existing webhook authorizer implementation did not support conditional logic, making it impossible to apply dynamic authorization policies based on request attributes.

This PR extends the webhook authorizer to interpret and enforce authorization conditions, enabling more precise access control by evaluating specified conditions during authorization checks.

Supporting conditional authorization in webhooks allows Kubernetes clusters to implement more flexible and context-aware security policies, improving overall access management.
