describe_resource have to return values with better format

[Kei Masumoto]

describe_resource functionality of python-novaclient is now on reviewing.
<https://review.openstack.org/#change,3457>

As a result of review, the return value of nova.api.openstack.compute.contribe.hosts.show() have to be changed slightly.

Currently, format of return values are depicted below.
> {u'host': {u'usage': {u'admin': {u'memory_mb': 6144, u'vcpus': 3, u'local_gb': 30},
> u'test005': {u'memory_mb': 2048, u'vcpus': 1, u'local_gb': 10}
> },
> u'resource': {u'vcpus_used': 1, u'local_gb_used': 45, u'memory_mb': 32234, u'vcpus': 16, u'local_gb': 128, u'memory_mb_used': 2013}
> }
>}

But it should be like this.
>{u'host': [{u'resource': {u'project': u'(total)', u'host': u'cb-blsv4a1', u'cpu': 16, u'mem(mb)': 32234, u'disk(gb)': 128}},
> {u'resource': {u'project': u'(used_now)', u'host': u'cb-blsv4a1', u'cpu': 2, u'mem(mb)': 2276, u'disk(gb)': 46}},
> {u'resource': {u'project': u'(used_max)', u'host': u'cb-blsv4a1', u'cpu': 2, u'mem(mb)': 4096, u'disk(gb)': 60}},
> {u'resource': {u'project': u'admin', u'host': u'cb-blsv4a1', u'cpu': 1, u'mem(mb)': 2048, u'disk(gb)': 30}},
> {u'resource': {u'project': u'test005', u'host': u'cb-blsv4a1', u'cpu': 1, u'mem(mb)': 2048, u'disk(gb)': 30}}
> ]
>}
