Without any parameters supplied openstack.cloud.baremetal_node_info is
supposed to gather and return information about all nodes.
This is done with a call to cloud.list_machines(), which itself calls
self.baremetal.nodes().
Unfortunately this will not return detailed information about each
machine as the details parameter of self.baremetal.nodes() defaults to
false.
This commit rewrites the module to use the baremetal service proxy of
openstacksdk to get machines with details and converts them using the
`to_dict()` method.
