The macos build fails with:

----------------
Note: The failure of target @envoy//source/extensions/filters/network/kafka:serialization_composite_code_generator_bin (with exit code 1) may have been caused by the fact that it is running under Python 2 instead of Python 3. Examine the error to determine if that appears to be the problem. Since this target is built in the host configuration, the only way to change its version is to set --host_force_python=PY3, which affects the entire build.

If this error started occurring in Bazel 0.27 and later, it may be because the Python toolchain now enforces that targets analyzed as PY2 and PY3 run under a Python 2 and Python 3 interpreter, respectively. See https://github.com/bazelbuild/bazel/issues/7899 for more information.
----------------
Target //src/envoy:envoy failed to build

This may be due to the only change in istio/envoy:release-1.3 that is picked up by this PR: istio/envoy#123

CC @fpesce @yxue who merged that PR.

[rlenglet]

@yxue any clue why this build fails?

[rlenglet]

@howardjohn would you be able to force-merge this PR? Only the macos test failed due to a wrong Python version. Getting this merged will unblock me to build 1.3.6. Thanks!

[rlenglet]

Will retry this later.
