feat(metrics): Add Fragment Level Exchange Metrics (#3696)

* Edit update.sh * Edit format error * Add payload to gitignore * Revert risedev.yml modification * Fix wrong gitignore * Fix wrong gitignore * Done coding for Fragment level exchange * Done coding for Fragment level exchange * Edit implementation error * Edit down fragment error * Delete println statement and revert configuration settings * Done coding for Fragment level exchange * Edit update.sh * Edit format error * Add payload to gitignore * Revert risedev.yml modification * Fix wrong gitignore * Done coding for Fragment level exchange * Edit implementation error * Edit down fragment error * Delete println statement and revert configuration settings * Edit Format and Resolve conflict * Resolve Test error * Resolve some error * generate dashboard * use rate_interval instead of 15s Signed-off-by: Alex Chi <[email protected]> Co-authored-by: Alex Chi <[email protected]>
