Move the release team meeting
With the new PTL and release we're moving the time for the meeting.
Following the poll at: https://doodle.com/poll/xxa46wrndefyi6dk ; and
discussion at: http://lists.openstack.org/pipermail/openstack-discuss/2019-April/004690.html
We've settled on:
AEST/AEDT, Australian Eastern Standard Time
5:00a Fri, Apr 19 2019 -> 6:00a Fri, Apr 19 2019
CEST, Central European Summer Time
9:00p Thu, Apr 18 2019 -> 10:00p Thu, Apr 18 2019
EDT/EST, Eastern Daylight Time (US)
3:00p Thu, Apr 18 2019 -> 4:00p Thu, Apr 18 2019
PDT/PST, Pacific Daylight Time (US)
12:00p Thu, Apr 18 2019 -> 1:00p Thu, Apr 18 2019
This isn't ideal but gets the whole team together, maintains alignment
with the 'Thursday US' weekly deadline and gives each member a full
workign day before the weekend.
