Lack of Configuration for Minimum Healthy Upstream Nodes in Health Checking

[Melod-YI]

I've noticed that in Envoy's health check configuration for upstream nodes, has no option to set a minimum number of healthy nodes. Like max_ejection_percent in outlier detection.

Since both health checking and outlier detection are mechanisms to identify and ejection unhealthy upstream nodes, I'd expect the health checking configuration to also provide options like "minimum healthy nodes" or "maximum unhealthy nodes" to control the behavior when the number of healthy nodes falls below or exceeds certain thresholds.

I'm wondering if there's a specific reason why such configurations are not available in Envoy's health checking, or if there are any plans to introduce them in the future. If there's a better way to achieve similar functionality, I'd appreciate any guidance or recommendations.
