Propose to add Takashi Kajinami as Oslo core reviewer

Hello everybody, It is my pleasure to propose Takashi Kajinami (tkajinam) as a new member of the oslo core team. During the last months Takashi has been a significant contributor to the oslo projects. Obviously we think he'd make a good addition to the core team. If there are no objections, I'll make that happen in a week. Thanks. -- Hervé Beraud Senior Software Engineer at Red Hat irc: hberaud https://github.com/4383/ https://twitter.com/4383hberaud
