### Motivation In the current topic level monitoring, there is no metrics to monitor the number of send data requests and the number of messages per send request (i.e., each entry) for a topic. This is inconvenient for us to troubleshoot the following issues: 1. In cases where the client does not perform batch data writing or the batch written messages are not very reasonable, we cannot intuitively reflect through monitoring and cannot detect unreasonable business usage in a timely manner; It has a significant impact on production and consumption performance, increasing cluster load, reducing cluster performance, and increasing overall costs; 2. When we enable the production flow limiting strategy, if the flow limiting condition is triggered by the number of requests on a single connection, it is difficult to accurately locate which topic's high-frequency send data is causing it; ### Modifications Add four metrics: `pulsar_request_rate_in`: Topic send request rate. `pulsar_average_msg_per_request`: Average number of messages per send request for topic. `pulsar_producer_request_in`: producer send request rate. `pulsar_producer_avg_msg_per_request`: Average number of messages per send request for producer. ### Does this pull request potentially affect one of the following parts: <!-- DO NOT REMOVE THIS SECTION.

GitHub Actions provides separate quota for pull requests that are executed in a forked repository. The tests will be run in the forked repository until all PR review comments have been handled, the tests pass and the PR is approved by a reviewer. --> -- This is an automated message from the Apache Git Service.
