[Bug 1578734] [NEW] Instance Creation fails because of Timeout and Duplicate Settings on NSX Edge (DHCP)

Public bug reported:

Using Openstack Liberty with VMware Driver / NSX Integration.

When deploying a Template with Heat (3 Instances, with 3 Security Groups, own Network)
The creation failes with an Error: no Hosts available.

But the main reason is a Timeout that occures between nova and neutron.
See the logs below.

For me it seems that Nova creates with Neutron a new Port in NSX (Create
DHCP reservation) , this times out, but the port gets created.

\n']

I can see, that the Edge DHCP, that has been created with HEAT,  has
also created a reservation for this machine.

Then, as the instance creation is rescheduled, it tries again to create
that port but fails, as the port is alredy configured on the Edge:

The environment consists of following:

Vsphere Version: 6.0.2
Openstack Liberty (Deployed from Mirantis)
There is only one Controller which includes all the Parts of Openstack (Nova, Neutron, Cinder, Glance, Horizon)

Thanks for any help to solve the Problem.
