Need to set resource_class on Ironic nodes after upgrade to Pike

[Dmitry Tantsur]

Nova changes the way it scheduled bare metal nodes, see https://specs.openstack.org/openstack/nova-specs/specs/pike/approved/custom-resource-classes-in-flavors.html for details. The first step is to make sure that we have node.resource_class populated in Pike. We can use "baremetal" for all nodes, as we use capabilities for more precise scheduling.

In Queens, we will also have to update our flavors according to the spec.

Update: we also need to adjust flavors. Otherwise random scheduling errors may come back due to nova changes planned for RC2.

    Set resource_class=baremetal for newly enrolled nodes

    We are switching to scheduling based on resource classes, so we need to set
    the correct resource class on all nodes from them to be picked.

    Switch to scheduling based on resource classes

    This is needed for upgrade. In the future we may support custom
    resource classes, but let's at least make sure we have one.
