Motivation

Pulsar Admin contains a command for analysing the topic backlog. However, the counters don't return the amount of marker messages. It would be useful to distinguish marker messages from ordinary messages.

Solution

• add the field to org.apache.pulsar.common.stats.AnalyzeSubscriptionBacklogResult
• add the counter logic to org.apache.pulsar.broker.service.persistent.PersistentSubscription#analyzeBacklog
