Proxying OVH’s Monitoring-Aware Scheduling

The team discussed OVH’s proposal to enhance scheduling decisions by integrating external monitoring data.
The idea is to add a filter or weigher that delegates its logic to an external plugin, allowing operators to plug in custom metrics (e.g., Prometheus, InfluxDB) without modifying Nova directly.

While the use case is relevant, existing out-of-tree filters and weighers already allow similar integrations.
One of the main challenges identified was how to share and maintain such code consistently across the community.

Current Nova interfaces likely already support this use case.
Proposal to create a dedicated repository on OpenDev for sharing and maintaining custom filters and weighers.
