(extensions) probes: create probe group, events: start work

[rafaeldtinoco]

This is the initial work of the Tracee Extensions, I'm preparing the baseline for #3170 (the multiple eBPF objects), which is a needed step for #2991 (API server) and the extensions:

Each extension will consist of:

1. Map Group    - eBPF maps used by this extension
2. Probe Group  - eBPF probes used by this extension
3. Functions    - tracee hooks callbacks
4. Event Group  - events declared by this extension
5. Signature(s) - signatures declared by this extension

Logic and packages will change. This is Work in Progress.

You had good and valid points. I did the changes and pushed, I'll consider you're still +1 as there are no other changes. Will merge if tests pass after the current bug fix release.

Thanks for reviewing this!

Some typos only @rafaeldtinoco, LGMT otherwise.

Thanks for reviewing, no matter the timing. I'll provide a chore PR with adjustments.
