Description PURANDHAR SAIRAM MANNIDI 2017-03-16 03:04:19 UTC 
Description of problem:
Orphaned namespaces remain after Neutron LBaaS stack deleted

Version-Release number of selected component (if applicable):
Red Hat OpenStack Platform 10

How reproducible:
Always

Steps to Reproduce:
(1) Create a Neutron LBaaS stack on RHOS 10
- neutron lbaas-loadbalancer-create subnet-one --name lbtest01
- neutron lbaas-listener-create --loadbalancer lbtest01 --protocol-port 80 --protocol HTTP --name testlistener01
- neutron lbaas-pool-create --name testpool01 --protocol HTTP --listener testlistener01 --lb-algorithm ROUND_ROBIN
- neutron lbaas-member-create testpool01 --address 192.168.1.2 --protocol-port 80 --subnet subnet-one
- neutron lbaas-member-create testpool01 --address 192.168.1.3 --protocol-port 80 --subnet subnet-one
- neutron lbaas-healthmonitor-create  --delay 3 --type HTTP --max-retries 3 --timeout 3 --pool testpool01

(2) Note the qlbaas namespace on the controller
- ip netns | grep qlbaas

(3) Delete the LBaaS stack
 - neutron lbaas-healthmonitor-delete <UUID>
- neutron lbaas-pool-delete <UUID<
- neutron lbaas-listener-delete <UUID>
- neutron lbaas-loadbalancer-delete <UUID>

(4) List the namespaces on the controller and observe the qlbaas namespace still exists
- ip netns | grep qlbaas

Actual results:
Namespaces are still visible

Expected results:
Namespaces should be removed when loadbalancer is deleted
