nova_compute_ironic container fails to start

[Yotaro Konishi]

When deploying nova_compute_ironic, current nova.conf.j2 generates two compute_driver options like this:

[DEFAULT]
compute_driver = ironic.IronicDriver
compute_driver = libvirt.LibvirtDriver

And the latter value is used by nova-compute service, which is not appropriate to nova_compute_ironic.

This bug was recently introduced in [1].

    Fix configuration for nova_compute_ironic

    Currently nova.conf.j2 generates two compute_driver options for
    nova_compute_ironic container like this:

    compute_driver = ironic.IronicDriver
    compute_driver = libvirt.LibvirtDriver

    nova_compute_ironic container fails to start because the latter value
    overrides the former one.

    This patch fixes the issue recently introduced in [1].
