Tail-based sampling: "internal" latency

[dhilgarth]

When sampling slow requests, I actually only care about whether they are slow in the environment I control, i.e. if they took longer than X from the moment they reached my gateway. I don't care if a request was slow, just because the users internet connection was slow.

Is there a way to achieve this with the existing policies?

An ignore list would be a simple way to add this capability to the latency policy: Ignore spans with these attribute values when calculating the latency.
