We propose adding the following new metrics:

NameDescription
kafka.server:type=broker-metadata-metrics,name=publisher-error-countReports the number of errors encountered by the BrokerMetadataPublisher while publishing a new MetadataImage based on the MetadataDelta 
kafka.server:type=broker-metadata-metrics,name=listener-batch-load-error-countReports the number of errors encountered by the BrokerMetadataListener while generating a new MetadataDelta based on the log it has received thus far.
kafka.controller:type=KafkaController,name=ForceRenounceCountReports the number of times this controller node has renounced leadership of the metadata quorum owing to an error encountered during event processing

Proposed Changes

ControllerForceRenounceCount and MetadataPublisherErrorCount
