Temporarily disable this check until we figure out why
operational_status sometimes does not become 'ONLINE'
while the member does indeed work and the subsequent
retrieval of payload through loadbalancer is successful
ref LP: #1896729.
Creating a load balancer consist of many independent API calls.
If any one of them fail today the whole job will be killed.
On failure to create a lb resoruce, clean up and retry.
The current test code for octavia requires DVR extensions to be
present on the Neutron API server.
We need to conditionally enable this based on enabled extensions to
allow the test to operate on multiple deployment configurations.
The existing code lead to intermittent failures as there are a few
Neutron ports tagged with ``device:owner`` ``compute:nova`` that
has nothing to do with our payload instances.
Get IP information by asking Nova to list instances instead.
