Description of problem:

When creating an instance, the value of the flavor is not displayed in the "flavor" column of the "openstack server list" command.

Version-Release number of selected component (if applicable):
openstack-nova-compute:16.0-80

How reproducible:
Create an instance using openstack cli, and then check the server list with the openstack server list command.

Steps to Reproduce:
1. Create an instance using openstack CLI (openstack server create myvm-1 --image cirros-OK --flavor m1.tiny --nic net-id=internal)
2.Execute "openstack server list" once it is active

Actual results:
flavor column is empty

Expected results:
flavor column should return "m1.tiny" value and display it

Additional info:

When the instance is created, the flavor column have information: | flavor | disk='0', ephemeral='0', , original_name='m1.tiny', ram='512', swap='0', vcpus='1' |

Also if "openstack server show e31b9e4c-3701-4d07-8a92-8b76520f325e" is executed, the flavor list is populated.
