[manila] no community meeting 27 December

As agreed at our last meeting, we will skip the regular manila community meeting on 27 December and resume our weekly cadence on 3 January 2019 at 1500 UTC on freenode #openstack-meeting-alt. All are welcome, and as usual please feel free to add to the agenda [1]. -- Tom Barron (irc: tbarron) [1] https://wiki.openstack.org/w/index.php?title=Manila/Meetings&action=edit§ion=2
