feat: use actuator/metrics for data points

Actuator metrics

Current

Previous

Other Actuator

This makes discussion easier as the links are available.

We can use de standard items and build custom

• use standard
• Through new issue make custom rock items available by their API like rserve.processes.current already there
• make UI table
• Add tests
• cleanup UI
• Align header same as Projects
• Add search to filter on
  • 
• Details clutters the table feel
  • 
  • Move Details in column as popout?
• odd/even on path difference .. detail above has 2 items on same path
• Bytes are rounded up to 2 digits precision B,KB,MB,GM,TB,EB
  • is similar nice to have for times ie uptime in days?

Weird error while testing on rserve.processes.current ... is that an actuator item?

As discussed. For now I'm not going to comment on the composition/options api. We will the refactor for that later. I do think we need tests and the typing should be fixed. Do you have the following plugins in your vsCode:
TypeScript Vue Plugin and Vue Language Features (Volar) ? I think it's the latter. I get error like these:

approve but please check if you can add smoketest for the '/actuator' and '/metrics'
I expect you would like to copy the test for the UserController
