This looks great already! I have some ideas for improvement! :)

Do you think we should ditch the --verbose flag? I would either remove it or make it a quiet flag. Users will be confused if there is no output for a minute when they just try to run the command.

[aeneasr]

I think also that a quiet flag makes more sense!

Great! Almost done! We need a page in the docs (maybe in guide?) which explains: "Choosing Argon2 Parameters". You could probably re-use the blog post!

Commit message:

feat: add helper for choosing argon2 parameters

This patch adds the new command "hashers argon2 calibrate" which allows one to pick the desired hashing time for password hashing and then chooses the optimal parameters for the hardware the command is running on:

```
$ kratos hashers argon2 calibrate 500ms
Increasing memory to get over 500ms:
    took 2.846592732s in try 0
    took 6.006488824s in try 1
  took 4.42657975s with 4.00GB of memory
[...]
Decreasing iterations to get under 500ms:
    took 484.257775ms in try 0
    took 488.784192ms in try 1
  took 486.534204ms with 3 iterations
Settled on 3 iterations.

{
  "memory": 1048576,
  "iterations": 3,
  "parallelism": 32,
  "salt_length": 16,
  "key_length": 32
}
```

Did you see the page I added in the troubleshooting/debug section?

I actually missed that and that page is very important. I still think it would make sense to have a guide for this also as it probably makes sense to first understand how to choose those parameters before the server crashes :)
