IMPALA-7924: Generate Thrift 11 Python Code
Upgrades the version of the toolchain in order to pull in Thrift 0.11.0.
Updates the CMake build to write generated Python code using Thrift 0.11
to shell/build/thrift-11-gen/gen-py/.
The Thrift 0.11 Python deserialization code has some big performance
improvements that allow faster parsing of runtime profiles. By adding
the ability to generate the Thrift Python code using Thrift 0.11 we can
take advantage of the Python performance improvements without going
through a full Thrift upgrade from 0.9 to 0.11.
Set USE_THRIFT11_GEN_PY=true and then run bin/set-pythonpath.sh to add
the Thrift 0.11 Python generated code to the PYTHONPATH rather than the
0.9 generated code.
Testing:
- Ran core tests
