Remove binding:profile modification from Mellanox ML2 driver

[Irena Berezovsky]

Mellanox networking solution requires knowledge of physical network during VIF plugging in nova.
Temporary work-around for Icehouse release was to use binding:profile to pass it.
During Juno release, patch to use binding:vif_details was added both on neutron and nova code.
vif _details dictionary on port:binding is used to pass physical_network information to nova and nova code gets physical network from vif_details.
It is about time to remove the work-around from the neutron code.

    Remove binding:profile update from Mellanox ML2 MD

    Remove temporary work-around that populates physical_network in
    binding:profile. Now when both neutron and nova use binding:vif_details
    to pass attributes to plug neutron port, this work-around is not nequired.
    Remove related temporary code from ML2 plugin.
