[Bug][Sort] The computing of Pulsar source metric was wrong

[gong]

What happened

Now, pulsar metric computing is just pulsar record, but record can be unpacked. We should compute unpacked data.
And, pulsar metric name is not right. We expect metric name is flink_taskmanager_job_task_operator_groupId_streamId_nodeId_numRecordsIn, but metric name is flink_taskmanager_job_task_operator_user_groupId_streamId_nodeId_numRecordsIn

What you expected to happen

metric result is right and metric name is right
