Title:
  In Arista ML2 delete tenant if no resources associated with it

Status in OpenStack Neutron (virtual network service):
  Fix Released

Bug description:
  When all resources for a tenant are deleted (ports and networks), the
  tenant is removed Arista's DB. This operation is performed during
  port/network_delete_precommit() operation. Arista's ML2 Sync mechanism
  used to ensure that the tenant is deleted from the back-end (i.e from
  Hardware) as well.

  With enhancements to the Sync mechanism to accommodate large scale
  deployments, it is prudent to move the deleting of tenant from
  port/network_delete_precommit() to port/network_delete_postcommit().
  This ensures that the tenant is immediately deleted from the DB as
  well as the back-end and removes the dependency on the sync mechanism.

  This bug is to make this fix.
