v1.1.0-kata-ci

Merge the latest changes from main and start 1.1 train:

- Bug fixes:
  - Allow running run-kata-perf-suite and clusterbuster using bash 4.2
  - Correctly handle NaN and infinity in JSON results from pods by
    converting them to null values.  Previously crashed the running
    job, which hung up clusterbuster.
  - Error out if we weren't able to retrieve the remote timestamp rather
    than hanging up.
  - Further cleanup improvements
- Functionality improvements:
  - Provide error messages for all forcible exits in clusterbuster.
  - Print logs of failed pods to stderr.
  - All CI profiles clean up namespaces by default.
  - Change "scaling" to "cpusoaker" in run-kata-perf-suite.
- Internal changes:
  - Separate run-kata-perf-suite and workloads in a manner similar to
    clusterbuster.
