The new GET to /placement/allocations is happening when the
resource tracker calls _update_usage_from_instance, which is always
being called becuause is_new_instance is always true in that method,
even when the instance is not "new". This is happening because the
tracked_instaces dict is _always_ getting cleared before
_update_usage_from_instance is being called. Which is weird because
it appears that it is that method's job to update tracked_instances.
If I remove the clear() the get on /placement/allocations goes away.
But I'm not sure what else this will break. The addition of that line
was a long time ago, in this change (I think):

I made a bug about this:
https://bugs.launchpad.net/nova/+bug/1659647
and have the gate looking at what breaks if the clear goes away:
