Default value for Physical Network is hardcoded value

[Janet Yu]

The default value for the "Physical Network" field in the "Create Network" form of the Admin dashboard, shown when the Neutron provider extension is supported, is "default". It makes more sense for the default to be blank instead of a hardcoded string.

    Removed default value for 'Physical Network'

    When creating a network there is currently a default value of 'default'
    which causes the network creation to fail. It is nonsensical to have
    a default value here as it will change depending on the provider
    network type and needs to be set according to custom settings if the
    user is not creating a simple local network which then does not require
    the physical network value at all.
