There are a patches that needs to be respin to target the new Pike

patches in merge conflict that needs to be rebased.
Searchlight integration
-----------------------
Listing instances
~~~~~~~~~~~~~~~~~
The list instances spec https://review.openstack.org/#/c/441692/ was
well discussed last week. There is still discussion about how to keep
the Searchlight data in sync with the Nova db with deleted or deleted
and archived instances.
It turned out that Searchlight still needs to be adapted to Nova's
versioned notifiations so the
https://blueprints.launchpad.net/searchlight/+spec/nova-versioned-notifications
bp is a hard dependency for the integration work.
bp additional-notification-fields-for-searchlight
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
4 patch from blueprint additional-notification-fields-for-searchlight
needs to be rebased due to merge conflict but the code seem ready to be
merged:
https://review.openstack.org/#/q/label:Code-Review%253E%253D1+status:open+branch:master+topic:bp/additional-notification-fields-for-searchlight
The blueprint needs discussion about how to model BlockDeviceMapping in
the instance notifications. I ran out of time last week so I will try
to draft the BDM payload object early this week.
Other items
-----------
Short circuit notification payload generation
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
The oslo messaging dependency has been merged and new oslo messaging
library release is promised early this week. So work soon be continued
on the nova patch https://review.openstack.org/#/c/428260/
bp json-schema-for-versioned-notifications
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
We shortly discussed that this feature might help keeping the
Searchlight data model in sync with the nova notification model.
However we still waiting for somebody to pick up the implementation
work behind the bp
