[neutron] Welcome Oleg Bondarev in the drivers team

Hi, Oleg is one of the most active and experienced developers around Neutron, and long served to be a member of the Drivers team (see: [0]). We all agreed that Oleg deserves to be part of the team and he will be a great member (see [1]), so I just added him to the neutron-drivers group. Welcome to the team Oleg!
