@tigrannajaryan Can you please take another look? It'd be great to have this (and the parent PR here) merged before or close to the Alpha announcement. |

Changes
Adds a data format description for OpenTelemetry profiles.
I took some content from the old OTEP but decided to leave all of the historical information out, both for clarity/focus and to improve readability (a technical specification doesn't read very well by nature).
We could add additional references and expand on design decisions in a future
