Nova doesn't support v3 when connecting to Ironic

[Clenimar Filemon]

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 404s) 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 filed 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.

    Support Identity v3 when connecting to Ironic

    This patch makes Nova:
    a) support Identity v3 params when creating an Ironiccient by
    creating a v3Password auth plugin and a Session;
    b) deprecate auth parameters admin_tenant_name, admin_username
    admin_password and admin_url;
    c) remove support to admin_auth_token auth parameter [1].

    [1] admin_auth_token was deprecated
    (317d9d8f13e8a34af189504ae1258d315154cc82) in favour of admin_username and
    admin_password (which are deprecated now in favour of username and
    password). More info at Keystone release notes (see Deprecation Notes
    and Security Issues):
