Bug 1772209

Description of problem:

When installing OCP 4.2 on OSP 15 with Kuryr, an internal Server Error happens when the following call is triggered to the Octavia API:

http://10.0.0.112:9876/v2.0/lbaas/loadbalancers?name=ostest-4jb2v-kuryr-api-loadbalancer&tags=openshiftClusterID%3Dostest-4jb2v&vip_address=172.30.0.1&vip_subnet_id=08b45410-5dcb-425a-a740-30
8cefcc322f

As described in the Octavia logs this seems to be an error when parsing the tags attribute:

2019-11-13 17:02:16.796 21 ERROR wsme.api [req-e3a0c6dd-0160-4034-be3c-7a8b9a926d85 - f95ccdb809df4674952ae92cca57e33a - default default] Server-side error: "Entity '<class 'octavia.db.base_models.Tags'>' has no property 'name'". Detail:

During handling of the above exception, another exception occurred:
