Correct REST API response fields for /os-migrations API

The compute APIs are unfortunately inconsistent with regard to the
response parameters for migrations.

* GET /servers/{server_id}/migrations returns server_uuid
* GET /os-migrations returns instance_uuid

Because the 'Server UUID' column is being specified for parsing the
response from GET /os-migrations, it is always showing as an empty
string to users.

There are a few other mismatches between the column names and the REST
API response fields [1]:

* 'Old Flavor' vs 'old_instance_type_id'
* 'New Flavor' vs 'new_instance_type_id'
* 'Type' vs 'migration_type'

This adds a new list containing the REST API response field names to
pass to utils.get_item_properties so that the responses are correctly
parsed and the client output contains the response data instead of
empty strings.
