PreprocessingException causes a crash when running on OpenShift spec downloaded from a live server

When the PreprocessingException is caught and this line is executed, https://github.com/openshift/openshift-restclient-python/blob/master/scripts/from_gen/preprocess_spec.py#L126, on Python 2.7 and 3.x it will raise an AttributeError because the .message attribute on BaseException was a deprecated feature only available in 2.6: https://sayspy.blogspot.ie/2007/05/baseexceptionmessage-is-now-deprecated.html . I can submit a pull request to fix this, it's straightforward. I don't know if the underlying error is something I should be worried about. The form I'm seeing it in my tests is:

scripts.from_gen.preprocess_spec.PreprocessingException: Cannot find listNamespacedServiceAccount

I've had a hard time replicating this issue. The systems I'm seeing this happen on is Python 3.5 on Ubuntu 16.04, but it's not reliable: one machine shows it, the other shows it only some of the time. My best guess is that there's nondeterminism because of dict iteration order, that the process of reading the spec somehow involves the network, or both.

I sent in a pull request to fix the Python 2.7+ crash upstream. I haven't been able to track down the underlying cause, and I don't think it's worth spending more time on since the script just logs the error.

We no longer support generating the modules. The new dynamic client and corresponding k8s module should be used instead of the generated modules.
