Open Stack

Hi folks

This patch was the culprit, so we have reverted it.
https://review.openstack.org/#/c/53459/1 (Note, this is revert of revert )

However even if it is reverted, the error happens

I tested tempest in local, it works with the patch and without patch.
# As you know, this is a timing issue.. so this doesn't mean there is no issue..

I'm reading logs, and I found some exceptions.

It looks like issue in IPAllocationRange.

My next culprit is the delete_subnet in ML2

Do you have any thought on this?
