[Bug 1603384] [NEW] [stable/liberty] LBaaS v2 haproxy:

 

Public bug reported:

Setup:
Single controller
1 KVM compute

Steps:

1. create subnet vn 20.0.0.0/24
2. Launch 4 instances on the above network
3. create LB1 for subnet vn. 
4. create listner and pool . Add instances as members to the pool
5. Try to delete the LBaaS port using neutron command

As port was LBaaS VIP port, neutron is showing below trace. It should
give some human readable error message to end user.
