There were a bunch of report client methods around updating inventory to
placement which were only being used in the non-update_provider_tree
code paths of the resource tracker's update routine. Those code paths
had already been retrofitted to produce a placement-shaped inventory
object.
update_from_provider_tree gives us another way to flush these inventory
changes.
This patch simply takes the inventory object produced by the
get_inventory() and update_compute_node() code paths and updates the
provider tree object in the same fashion as update_provider_tree does.
So now all three code paths can commonly invoke
update_from_provider_tree.
And we can get rid of a ton of redundant code in the report client.
This includes the former incarnation of set_inventory_for_provider; so
we rename the artist formerly known as _set_inventory_for_provider to
match its brethren, set_traits_for_provider and
set_aggregates_for_provider.
