Deleting a non-existing member deletes the actual member

[Banashankar]

How to reproduce.
1. Create a member

2. Delete it using correct member id

3. Create one more member

4. Use the member id created in 2nd step to delete the member. It deletes the member created in 3rd step.

well this is a weird one

We were able to replicate the bug

The bug is in LBassV2 and not in Octavia

The bug is in the filtering method that lists the members::

It doesn't matter what you set for ID you get the list of memebrs::

fields=id&name=test will give you the entire list of members

The bug was fixed in LBaasV2 during November / December 2015 ... refreshing environment to latest LBaasV2 version to validate that the bug is invalid.

[Eran Raichstein (eranra)]

Exposing with the latest version of Neutron-lbaas (and latest octavia and neutrun) and the behavior was fixed. We get
error message as expected (Unable to find member with name '0b02a6cb-a669-422b-8e3e-65cfa9697c12')
