Public bug reported:

nova-ironic communication only supports v2, deprecated auth parameters,
e.g [1]. this will cause a fatal error during a v3-only devstack setup,
as ironic keeps waiting for nova to provide resources and a timeout
occurs (logs will show a lot of 401s) failing the setup.

currently an ironic-enabled, v3-only devstack setup will fail because
ironic itself doesn't support v3, but we already have a filled bug [2]
and a patch on the way [3].

to reproduce this issue: setup a v3-only devstack with patched [3]
ironic enabled. it should fail waiting for nova-hypervisor to provide
VMs.
