 Description   

We need to be able handle highest version for both plugin and device, but if we will use only some features from OFP 1.5 we can call it as 1.3 enhancement but we need to be able to know the device is capable of work with protocol 1.5

Actually, we accept in ofjava only OF messages in version v1.0/1.3.
https://git.opendaylight.org/gerrit/#/c/26087 will allow any version of Hello message for negotiation (up to v1.5). With this we could know the highest supported version by device however after successful handshake we should not communicate in other version than negotiated.

If we want to use features from higher versions there are some official extensions for v1.3 including for example bundles from v1.4/1.5 (https://www.opennetworking.org/images/stories/downloads/sdn-resources/onf-specifications/openflow/openflow-extensions-1.3.x-pack2.zip). Another possibility is support higher protocol versions.

...at this time I'm going to investigate also ofplugin side of handshake.
