This PR avoids sending out full UpdateMetadataReuqest in the following scenarios: 1. On broker startup, send out full UpdateMetadataRequest to newly added brokers and only send out UpdateMetadataReuqest with empty partition states to existing brokers. 2. On broker failure, if it doesn't require leader election, only include the states of partitions that are hosted by the dead broker(s) in the UpdateMetadataReuqest instead of including all partition states. This PR also introduces a minor optimization in the MetadataCache update to avoid copying the previous partition states upon receiving UpdateMetadataRequest with no partition states.
