[venus][ptg] Xena PTG

Hi, Venus is the OpenStack project that provides a one-stop solution for log collection, indexing, analysis, alerting, visualization, report generation and other needs. Additionally, this project plans to use machine learning algorithms to locate failures and find the root causes quickly, to improve operation and maintenance efficiency. If you are planning to attend venus sessions during the Xena PTG, please fill in the doodle[1] with time slots which are good for you before 23rd March so that we can book the best time slots for most of us. And, please add any topic which you want to discuss on the etherpad[2]. [1] https://doodle.com/poll/q72urs2mk7up45pf [2] https://etherpad.opendev.org/p/venus-xena-ptg
