4073: Simplify Puffin report exports r=ManyTheFish a=Kerollmops
This PR changes how we export Puffin reports by directly writing them to disk when the `exportPuffinReports` [experimental feature is enabled](https://www.meilisearch.com/docs/learn/experimental/overview) on the `/experimental-features` route. It also adds more puffing logging to the deletion phase and grenad helpers. The puffin reports are identified by the date and time at which they are exported.
## Todo List
- [x] Change the CLI flag to be an API experimental option.
- [x] Create [a PRD for this experimental feature (private)](https://www.notion.so/meilisearch/Export-Puffin-Reports-091df151e71c4edfb7d72f4bf995b3ea).
- [x] Create and complete [a product discussion](https://github.com/meilisearch/product/discussions/693) (copy/paste PROFILING markdown?).
- [x] Update the _PROFILING.md_ markdown file instructions.
- [x] Change the debug logs of the processing operation (visible in puffin viewer).

4089: Use a bufreader and bufwriter everytime there is a grenad<file> r=curquiza a=irevoire
# Pull Request
Wrap all the files we give to a grenad in a `BufReader` or `BufWriter`.
The dump import I tried in the issue went from 2h to 10 minutes on my machine.
I also ran a bunch of benchmarks on my machine, and we're faster by a few seconds everywhere but nothing huge.
-----
The one thing I’m afraid about is if we used to get the inner file in a grenad and then do a read right after without a seek at the beginning of the file or a reopen.
Since we now use a bufreader our read would return the bytes one buffer later and probably completely corrupt what we were supposed to read.
From what I see, it looks like it works, but I may have missed something, I don't know much about this part of the codebase.
This issue should not arise on the bufwriter, though, because if we're not able to write the content of the buffer I ensured that the `into_inner` of the bufwriter should return an internal error.
