### Motivation In the existing solution there's a memory leak that occurs when a lookup request doesn't receive a reply. The timeout handling doesn't remove the lookup request's future from pending requests. https://github.com/apache/pulsar/blob/9db880eddb4bcd4478e24d5161ec022991cd5da7/pulsar-client/src/main/java/org/apache/pulsar/client/impl/ClientCnx.java#L615-L621 ### Modifications There's a common way to handle request timeouts in ClientCnx class . However, this method wasn't used for lookup requests. This PR makes changes in lookup request timeout handling to use the common way which uses the `requestTimeoutQueue` based solution. Another modification is to use `System.nanoTime()` for calculating elapsed time since `System.currentTimeMillis()` is not a stable way to calculate elapsed time. -- This is an automated message from the Apache Git Service.
