[v4]

Feature:
- Add the JVM related metrics
- Support to choose by datasource, job and instance
Fix:
- Remove duplicated metrics: e.g., write_batch_time_in_commit_processor
Improvement:
- Use rate() to react the fluctuation of data for total time summary metric
- Have a better classification by checking the source codes to know what every metric wants to do
- The metrics in the CommitProcessor are placed the same order with the source code for a better observation for the workflow of CommitProcessor
- Use an unit(e.g., ms/byte) for metric graph
- Prioritize the metrics in the same panel
Compatibility Test: - Tested with grafana-6.x(6.2.2); grafana-7.x(7.0.5)
