 * A priority that can be assigned to a request by implementing the {@link RequestPrioritizer}.
 * There is 5 statically defined priority levels:
 * 
 * critical: this request should almost never be rejected
 * important: this request should only be rejected under high load
 * normal: this is a normal request
 * background: this is a background request, it may be rejected if needed
 * degraded: this request may be rejected freely
 *
