[tacker] PTG planning

Hi Tacker team,

I've updated our vPTG etherpad for topics you've proposed [1]. We will start it from 27 Oct 6am UTC. So, I would like to skip the next IRC meeting this week. You can find Tacker's room on Zoom from schedule tracks here [2].

I'd also like to ask you to join in taking team photo on our 2nd day, although it's not mandatory.

Thanks, Yasufumi
