Add introduction guide for profiling with eBPF and a simple project

[maxgio92]

Hello,
I wrote an introduction guide to profiling leveraging frame pointers with eBPF [1]. The guide references a simple profiler I wrote [2] for learning purposes, and it's part two of a series [3] about profiling with frame pointers.

Because there are a lot of excellent profilers but at that time I wanted to write a simple one to study, I named it Yet Another Profiler (YAP). The profiler supports as of now ELF binaries that are not stripped, and that are compiled with frame pointers.

The guide [1] and the project [2] could be a companion for people willing to learn in this field of observability and eBPF.
Let me know what you think :-)
Thank you.

Hi, sorry for the delay, I meant to reply and then it slipped out of my mind.

The blog posts are interesting, nice! I'm OK to add a link if you're willing to do a PR. I would maybe not add a link to the GitHub repo itself, given that it's linked from the blog posts already.
