The os-hosts API uses different attribute names depending on whether the host was returned as part of a list or not. A host returned from 'show host' has the attribute "host" whereas a host returned from 'list hosts' has the attribute "host_name". This adds a host_name property to the Host class that will set the "host" attribute if necessary. Although this doesn't exactly mirror the responses coming back from nova api, it will make it easier for users to use the objects interchangeably for hosts.list() operations and hosts.update() operations, for example.
