dotnet trace as client for pyroscope (format)

[benaadams]

Background and Motivation

dotnet trace collect generates large files while tracing so it is more for taking snippets of activity rather than continuous monitoring.

Proposed Feature

If it could act as a Pyroscope Agent then it could be stored in the highly compressed pyroscope format allowing for tracing to operate over much larger time periods (months/years) see: https://github.com/pyroscope-io/pyroscope/blob/main/docs/storage-design.md

data type	bytes
raw data	93
tree	58
tree + trie	10

Currently they have clients for Ruby, Python, Go, Linux eBPF and are working on Node. Would be great to have .NET as one of the options too

(Raised issue in pyroscope regarding this too grafana/pyroscope#117)

Dmitry from Pyroscope here. We're gonna document the API soon, there's an issue about it on our side grafana/pyroscope#83

I'll post an update here as soon as we have that done.
