Subject: lib/base: allow for results parsing on non-zero return code

On an 'oc get' in particular, the command may return a non-zero
error code while still having found valid resources. Thus, we should
parse the valid output while still reporting the error. oc_obj.get(),
for instance, takes care of determining if the return code should be
reset to 0 in some error cases.

Also do a bit of logic cleanup and output sanitizing.
