[neutron][PTG] Schedule for yoga PTG

Hi, I made a first schedule for the PTG next week, please check it: https://etherpad.opendev.org/p/neutron-yoga-ptg If you have anything to change or add please raise your voice :-) There's still some parts which can change, as we will have multiple cross-project sessions. See you next week. Lajos Katona (lajoskatona)
