So far there have been some sanity tests that failed on Octavia jobs
that run Tobiko.
Octavia currently does not have any sanity test, and whenever Octavia
will have any, Octavia jobs will run those specific ones.
Currently they simply make Octavia jobs unstable, and take some time,
without much (or any) benefit, yet.
This patch removes the sanity tests from the Octavia faults workflow.
