Ryota MIBU 842d54a299 use openstack command instead of nova command ...

In function 'get_instance_ip', 'nova' client command is used to get
instance information in order to retrive IP address of the instance.

There is no need to use the nova command, since 'openstack' client
already supports such basic operation.

Moreover, 'openstack' client has an option to get value of specified
column. That brings more accurate way of retriving IP address.

This patch replaces nova command in 'get_instance_ip' by 'openstack'
command. Note, this nova command is the only one in devstack tree.
