Resource Provider Weigher and Preferred/Avoided Traits

The proposal introduces a resource provider weigher to influence scheduling decisions, with a longer-term goal of supporting preferred and avoided traits.
This would allow external services, such as Watcher, to tag compute nodes (e.g., with CPU or memory pressure) and guide the scheduler to favor or avoid specific hosts.

There are concerns about validating the weigher’s behavior at scale, ensuring it works correctly with a large number of instances.
Continue developing this approach.
Improve the test framework, despite existing challenges.
Add Monte Carlo–style functional tests to validate behavior in complex, non-symmetric scenarios.
