  Add 3 metrics for s390 machines:
- Cycles per instruction: Amount of CPU cycles used per instructions,
  named cpi.
- Problem state ratio: Ratio of instructions executed in problem state
  compared to total number of instructions, named prbstate.
- Level one instruction and data cache misses per 100 instructions,
  named l1mp.

For details about the formulas see this documentation:
https://www.ibm.com/support/pages/system/files/inline-files/CPU%20MF%20Formulas%20including%20z16%20-%20May%202022_1.pdf
