Instead of producing our own error message, we can show the original
value and the error from strconv.
This is a verbatim copy of the corresponding files in csi-test v4.0.2.
They'll be modified in future commits to make the code usable when
embedded in e2e.test. Some of those changes may be worthwhile
backporting to csi-test, but this is uncertain at this time.
We don't need much concurrency and having too many worker threads has
one disadvantage (besides resource usage): when the sidecar looses the
connection to the CSI driver, it calls klog.Fatal, which prints all
gouroutines. This can lead to much output.
The test should run for test drivers which support dynamic
provisioning, but was skipped because of the volume type check:
