jumbo_frame: Add jumbo frame support
Add jumbo frame support for all packet forwarding applications
inside guest for pxp testing. Enable jumbo frame support for
OvsVanilla, OvsDpdkVhostUser, and Packet forwarding.
Add minor fix for missing method issue when running packet
forwarding tests. The get_version method was missing in
the packet_forwaring core module.
