Run the rotating node test as specified in RELEASES.md (using the infra existing in qa-infra), fix any found issue, compare with v0.37.0 results. Finally populate the rotating node section of the v0.38.x report.

• Set up the DO testbed
• Run the test: loader set up using the saturation point found in the 200 node test
• Obtain the relevant prometheus plots
  • Compare them to those obtained for v0.37.0
• Write corresponding section of the QA report
  • qa: rotating node test on v0.38.x #883

DoD:

• No showstopper bugs found remain unresolved
• Rotating node section of the QA report is merged into main and v0.38.x
• No unacceptable performance regression detected (usually > 10% degradation w.r.t. v0.37.0
