Title:
  create_and_delete_subnets rally test failures

Status in OpenStack neutron-gateway charm:
  New
Status in neutron:
  Invalid

Bug description:
  NeutronNetworks.create_and_delete_subnets is failing when run with
  concurrency greater than 1.

  Here's a snippet of a failure: http://paste.ubuntu.com/25927074/

  Here is my rally yaml: http://paste.ubuntu.com/26112719/

  This is happening using pike on xenial, from the ubuntu cloud
  archive's.  The deployment is distributed across 9 nodes, with HA
  services.

  For now we have adjusted our test scenario to be more realistic.  When
  we spread the test over 30 tenants, instead of 3 and if we simulate 2
  users per tenant, instead of 3, we do not hit the issue.
