Public bug reported:

After I add service_provider to neutron.conf with multiple
service_provider enabled plugins, 'neutron service-provider-list'
returned duplicated entries.


Here is neutron.conf snippet which makes problem and output of the command.

[DEFAULT]
service_plugins = l3_router,neutron_lbaas.services.loadbalancer.plugin.LoadBalancerPluginv2

[service_providers]
service_provider = LOADBALANCERV2:Octavia:neutron_lbaas.drivers.octavia.driver.OctaviaDriver:default


openstack network service provider list
+----------------+-------------+---------+
| Service Type   | Name        | Default |
+----------------+-------------+---------+
| LOADBALANCERV2 | octavia     | True    |
| L3_ROUTER_NAT  | single_node | False   |
| L3_ROUTER_NAT  | ha          | False   |
| L3_ROUTER_NAT  | dvrha       | False   |
| L3_ROUTER_NAT  | dvr         | False   |
| LOADBALANCERV2 | netscaler   | False   |
| LOADBALANCERV2 | octavia     | True    |
| LOADBALANCERV2 | netscaler   | False   |
+----------------+-------------+---------+


As you can see there were duplicated LOADBALANCERV2 typed providers. After digging the related code, there is no filtering logic in ProviderConfiguration class at all using service type (named svc_module in __init__()). 

I think there should be filtering logic at ProviderConfiguration or
NeutronModule class.
