Skip LoadBalancerScenarioTest for octavia

Currently above test is failing with following error
```
Policy does not allow this request to be performed.
```
It is blocking wallaby check and gate patches.
The fix is already availble in component line, we need
a wallaby promotion to fix it.
Till then we are skipping the test to unblock the gate.
