      Description

      Seems a couple unhandled cases following sensor expiration:

      1. Static sensors (such as ClientQuotaManager.delayQueueSensor) can be expired due to inactivity, but the references will remain valid and usable. Probably a good idea to either ensure we use a "get or create" pattern when accessing the sensor or add a new static registration option which makes the sensor ineligible for expiration.
      2. It is possible to register metrics through the sensor even after it is expired. We should probably raise an exception instead.
