Granular Resource Request Syntax
As generic and Nested Resource Providers begin to crystallize and be exercised, it becomes necessary to be able to express:
Requirement 1: Requesting an allocation of a particular resource class with a particular set of traits, and requesting a different allocation of the same resource class with a different set of traits.
Requirement 2: Ensuring that requests of certain resources are allocated from the same resource provider.
Requirement 3: The ability to spread allocations of effectively-
This specification attempts to address these requirements by way of a numbered syntax on resource and trait keys in flavor extra_specs and the GET /allocation_
