[nova] spec review day

Hi, During the today's meeting it came up that we should have a spec review day around M1 (and later one more before M2). As M1 is 27th of May, I propose to do a spec review day on 25th of May, which is a Tuesday. Let me know if the timing does not good for you. The rules are the usual. Let's use this day to focus on open specs, trying to reach agreement on as many thing as possible with close cooperation during the day. Cheers, gibi
