Need change host to host_name in host resources

[tinytmy]

step to reproduce:
In python Terminal ,
>>> from novaclient.v1_1 import client
>>> ct = client.Client("admin","password","admin","http://192.168.1.100:5000/v2.0")
>>> ct.hosts.get("hostname")

error:
File "<stdin>", line 1, in <module>
  File "/opt/stack/python-novaclient/novaclient/v1_1/hosts.py", line 24, in __repr__
    return "<Host: %s>" % self.host_name
  File "/opt/stack/python-novaclient/novaclient/openstack/common/apiclient/base.py", line 464, in __getattr__
    raise AttributeError(k)
AttributeError: host_name

This is a python-novaclient bug, not a nova bug

In the nova code,
https://github.com/openstack/nova/blob/master/nova/api/openstack/compute/contrib/hosts.py?100#L100
there used host_name,
I think this need to unify, if we change the host to host_name, it also solve this problem. Maybe we can change the python-novaclient to solve this problem, but i think change this bug in nova is much better.
