Create Grafana dashboard of COIN workitems

solution:
dashboard
https://testresults.qt.io/grafana/d/DQHnzeK4z/ci-metrics-coin-capacity?orgId=1

scripts:
https://git.qt.io/anwojcie/grafana_scripts/-/tree/main/coin_capacity

The purpose is track the COIN HW usage. We have HW resource pools:

• Linux&Windows (kvm) pool
• MacOS Intel (parallel) pool
• MacOS 11 ARM (jenkins) pool
• MacOS 12 ARM (jenkins) pool

Idea is to have on dashbord for each of them.

Generic requirements for the dashboards

X-axis is time
Y-axis is capacity used (= cpu count * duration), unit is CPU/h

It needs to be possible select grouping data ("split the y-axis") by

• type (integration, precheck, scheduled build, RTA run, MCU build, packaging run)
• project
• branch
• tasktype (build, test)

It needs to be filter the data shown by

• project
• branch
• host OS
• operating system version
