Cannot start instances with neutrons multi-provider network

[Vladik Romanovsky]

Instances utilizing SR-IOV won't be able to start with a network port that has been created from a multi-provider (multi-segment) network. [1]

Such ports will have a special "segments" field that will hold a list of networks and will fail when we will attempt to retrieve a single network, such as here [2]

    neutron: retrieve physical network name from a multi-provider network

    Multi-provider networks are a combination of vxlan and vlan networks.
    such a network has a special "segments" field that holds a list
    of networks. Each element of this list has the same structure as the 'provider
    network attributes'.
    These attributes are:
    - provider:network_type
    - provider:physical_network
    - provider:segmentation_id

    This patch will retrieve the relevant physical network name from a
    multi-provider network
