Comment 1 for bug 1905219

1. I don't think we ever saw this happening, can you elaborate?
2 We have this part of code that's being run periodically: https://github.com/openstack/kuryr-kubernetes/blob/master/kuryr_kubernetes/controller/drivers/vif_pool.py#L482. Do you think it doesn't work? Do you use nested or neutron VIF driver?

3. Right, it may make sense to delete them there, though binding_failed is most of the time indication of some Neutron issues, so underlying cluster might be just broken.
