      Description

      The RM will renew tokens 90% of the way to the next expiration. When the max lifetime is approaching, the next expiration is always the max lifetime. The RM starts to unnecessarily renew more and more frequent as that hard limit approaches. The RM should stop renewing when the last expiration matches the new expiration.
