[Feature] latency-based failover

[wanlce]

What feature you would like us to integrate into the daed project

Latency-based failover is already implemented in dae, no add_latency related configuration is found in daed.

Why is this needed

The add_latency can be set in daed.

Sorry for the late reply, I want this feature as well. But we are lacking upstream endpoint API support. So... there's that.
