The os-baremetal-nodes compute API does not proxy
baremetal node create/delete or interface add/remove
requests to Ironic, so there is no point in even
having CLIs or python bindings for these operations
in the client.
There isn't a point in deprecating these since they
are already unusable, so let's just remove them.
