Description Jakub Libosvar 2019-06-03 15:23:01 UTC 
Description of problem:
neutron_tempest_plugin.api.admin.test_shared_network_extension.RBACSharedNetworksTest.test_duplicate_policy_error tests that an attempt to create an existing network rbac policy fails with proper error. Client expects a conflicting response from the server, however client bails out after it hits HTTP timeout with 504 code and following message "<html><body><h1>504 Gateway Time-out</h1>\nThe server didn't respond in time.\n</body></html>\n"

The reason is that the retry mechanism in Neutron is triggered when there is an existing entry in the database, hence Neutron keeps trying to create the entry 20 times.
