A local devstack test with
USE_PYTHON3=True
DEVSTACK_GATE_USE_PYTHON3=True
and
PROJECTS="openstack/barbican $PROJECTS"
enable_plugin barbican https://opendev.org/openstack/barbican
blew up because uwsgi tried to run under py2.
The dep sets USE_PYTHON3 to True by default, which may or may not be
sufficient to expose $problems, but let's see.
[Later] We think the (legacy) grenade-devstack-barbican job was failing
because it was trying to "upgrade" from py2 to py3 and running into
packaging conflicts. This explicitly sets DEVSTACK_GATE_USE_PYTHON3=True
in that job to resolve the problem.
