Add "logout script" for interactive shell

[Daudre-Vignier-Charles]

Related problem

In ZSH or Bash, I can execute scripts/commands when I close the interactive shell. In Bash and ZSH this functionnality is given by a script file, respectively ".bash_logout" and ".zlogout". Code inside this file is executed while the shell is closing. It seems that this functionnality doesnt exist in Nushell.

Describe the solution you'd like

Add any kind of functionality that allow code to be run while the shell exit.

Describe alternatives you've considered

Additional context and details

Simple usage case :
While using the shell I use custom commands to populate in-memory database. I can initialise the database in the config.nu file for example but I cannot automaticaly save the database when exiting the shell.
This can be useful too for some cleaning like deleting temp files.

I don't know if this is the right place for a hook, but maybe that's another option - just having an exit hook.

Have to watch out for exit() gotchas
