Remaining work on shared resources for Pike

Registered by Jay Pipes on 2017-02-14

Few things need to be completed for the shared resources work in Pike:

1) Rename "can_host" to "shared" on placement DB's resource_providers table
  (edit mriedem): Per discussion at the Pike PTG, this needs to change since we're going to use traits now: https://review.openstack.org/#/c/376198/
2) Add InventoryList.get_all_by_aggregate_uuid()
3) Expose GET /aggregates/{uuid}/inventories
4) Integrate in reporting client the allocation consumption from the shared resource providers of disk
5) Add a bunch of functional tests

I'm closing this out for Pike since there are no open changes and the #4 in this list was handled by https://blueprints.launchpad.net/nova/+spec/placement-allocation-requests. -- mriedem 20170707

Actually given bug 1707256 I'm going to say we can't yet support shared storage so I'm marking this as not completed. -- mriedem 20170804

Deferring this to Queens.

Per the Queens PTG discussion on priorities for Placement:

http://lists.openstack.org/pipermail/openstack-dev/2017-September/122233.html

We have agreed to defer this to Rocky. -- mriedem 20170919
