This patch updates our Popen calls to enable universal newlines for calls that we parse or consume the output for. Without univeral_newlines=True, the output is treated as bytes under python3 which leads to issues later where we are using it as strings. See https://docs.python.org/3/glossary.html#term-universal-newlines Change-Id: I1a9edd0ebac6f0539ac5c33056c442cfcfafb7f3 Related-Blueprint: python3-support
