Split write and ingest throughput

[JaySon-Huang]

Signed-off-by: JaySon-Huang tshent@qq.com

What problem does this PR solve?

Issue Number: close #4243

Problem Summary: Now the "Write Throughput By Instance" panel mixes the throughput of write and ingest, which is not easy to check whether the write throughput of each instance is balanced or not. And is not easy to check when we are scaling-in or scaling-out TiFlash instance.

What is changed and how it works?

• Split "write" and "ingest" into different lines in "Write Throughput By Instance"
• Rename "throughput_write" to "throughput_write+ingest" in "Write & Delta Management Throughput" to indicate that include "write" and "ingest" explicitly. Cause we care about foreground write and background delta-management is matched or not in that panel.

Scale-in one node and scale-out another node
