Nova driver does not read hosts table

[Alexander Yip]

In nova_driver.py::update_from_datasource(), there is a comment that disables the hosts table.

        # TODO(thinrichs): debug and re-enable
        # self._translate_hosts(self.nova_client.hosts.list())

Figure out why and uncomment this line.

host translation works fine, so i am re-enabling it.

Here is the data being populated by CLI

openstack congress datasource table list nova

+--------------+
| id |
+--------------+
| flavors |
| hosts |
| floating_IPs |
| servers |
+--------------+

openstack congress datasource row list nova hosts

+-----------+-----------+----------+
| host_name | service | zone |
+-----------+-----------+----------+
| mvista | conductor | internal |
| mvista | network | internal |
| mvista | scheduler | internal |
| mvista | compute | nova |
+-----------+-----------+----------+

Sounds good. I'll take a look at the code review.
