ResourceProviderTraits - Manage Capabilities with ResourceProvider
The ResourceProvider has a collection of Inventory and Allocation objects to
manage the *quantitative* aspects of a boot request: When an instance uses
resources from a ResourceProvider, the corresponding resource amounts of
Inventories are subtracted by its Allocations. Despite the quantitative
aspects, the ResourceProvider also needs non-consumable *qualitative* aspects
to differenitiate their characteristics from each other. We need a way to
represent the missing piece of ResourceProviders, so we propose a new REST
resource `traits` in placement API to manage the qualitative parts of
ResourceProviders. Using Traits API, the placement service can manage the
characteristics of resource providers by Traits, and then help scheduler make
better placement decisions that match the boot requests.
