When writing these modules, ofagent team (kakuma, yamamoto) thought that @author tag was OpenStack's style to represent authorships. But it turned out to be wrong. Acutally there seems to be a consensus not to use them. So, replace them back to the original Ryu-style copyright notices. Change-Id: Icc9fdd1850c0c1dbd354bb3312199a7f6849925a
