Negative acknowledgement number of retries

**Is your feature request related to a problem? Please describe.**
In actual use, if it still fails after a certain number of retries, put it in a dead letter. At present, if the dead letter queue is not configured, it seems that it will always try again. If a cancel confirmation is configured, it will be put into the dead letter.

**Describe the solution you'd like**
The number of retries can be configured.

**Describe alternatives you've considered**
Refer to other MQ retry strategies and dead letter strategies.

**Additional context**
Add any other context or screenshots about the feature request here.

The issue does not name any files, tests, or entry points. Start by tracing Pulsar's retry and dead-letter handling, then define how a configurable retry count should behave when no dead-letter queue or cancel confirmation is configured; done means the retry limit is configurable and failed messages follow the intended dead-letter behavior.
