sdnoverlay + flannel should have extra EndpointPolicy in config

[adelina-t]

In order for flannel + sdnoverlay to work in overlay mode this extra endpoint policy should be added:

{
            "Name":"EndpointPolicy",
            "Value":{
               "Type":"ProviderAddress",
               "Settings":{
                  "ProviderAddress":"host ip"
               }
            }
         }
