Disable Swift in Heat Python3 job
Devstack doesn't check for classifier anymore, and Swift doesn't support
python3 yet. Let's make it use python2 for now in the non voting job.
if [ "{special}" == "-py35" ] ; then
export DEVSTACK_GATE_USE_PYTHON3=True
+ export DEVSTACK_LOCAL_CONFIG+=$'\n'"disable_python3_package swift"
else
export DEVSTACK_GATE_USE_PYTHON3=False
