These fields need to be set by OpenStack, otherwise there is the
potential to create severe errors. They also require admin/owner
permission to set. They should not be exposed to end users at all.

There is duplicate logic on how ports for machine interfaces are
created. This converts all portCreate calls to use a single private
function to create ports and uses the same process for each of them.

Allowed address pairs and security groups are now removed from the port
when the port security is disabled. This ensures that no nova errors
occur since this is a hard requirement of diabling port security.

The yaml for the vnic type required an argument "binding:vnicType" when
it should have been "vnicType". The HostID had the same issue. We also
created a struct for the FixedIPs to ensure the api remains camel case.
