This puts all of the thrift-generated python code into the impala_thrift_gen package. This is similar to what Impyla does for its thrift-generated python code, except that it uses the impala_thrift_gen package rather than impala._thrift_gen. This is a preparatory patch for fixing the absolute import issues. This patches all of the thrift files to add the python namespace. This has code to apply the patching to the thirdparty thrift files (hive_metastore.thrift, fb303.thrift) to do the same. Putting all the generated python into a package makes it easier to understand where the imports are getting code. When the subsequent change rearranges the shell code, the thrift generated code can stay in a separate directory. This uses isort to sort the imports for the affected Python files with the provided .isort.cfg file. This also adds an impala-isort shell script to make it easy to run.
