[Backport 2024.2] fix(test-case): update 5000 tables test case configuration #9846

Merged

List of changes:

  • Disable per-table metrics due to significant perf impact.
  • Enable cluster health checks which work with this case just fine.
  • Decrease the nemesis interval from 60 minutes to just 3 keeping in mind that health checks will take some time too.
  • Reduce stress time for each of the 5000 commands. Having 20 minutes per cmd we will get about 1.5 days long test runs instead of the 2.5 days.
  • Reduce number of loaders from 5 to 3 to use resources more efficiently. In current case the bottleneck is the RAM.

Note that this scenario hits following bug:

If destroy_data_then_repair nemesis gets triggered aganst the setup of this scenario.
