MINOR: spoe: Add "max-frame-size" statement in spoe-agent section

As its named said, this statement customize the maximum allowed size for frames
exchanged between HAProxy and SPOAs. It should be greater than or equal to 256
and less than or equal to (tune.bufsize - 4) (4 bytes are reserved to the frame
length).
