Extending versioned notifications for searchlight integration

Registered by Balazs Gibizer on 2017-08-07

This is a continuation of the work started in Pike under the bp https://blueprints.launchpad.net/nova/+spec/additional-notification-fields-for-searchlight

Workitems:
* Optimize db usage when including BDM to instance notifications. Use the already in scope BDM instead of reading BDM from the db. A patch series are starts here https://review.openstack.org/#/c/483324/

As Searchlight seems to going away as a project we are not intended to do the below addition until some other consumers requests it.
  * Add 'status' field for the instance notifications. See the discussion on the ML
    http://lists.openstack.org/pipermail/openstack-dev/2017-July/119891.html There is WIP patch with
    the solution but we are running out of time with that https://review.openstack.org/#/c/485525/
