Feature Request

According to #249 (comment) the wp user reset-password command ist intended to reset, the user's password (e.g. to handle a password breach)

In this scenario it is required to reset all passwords for all users. Therefore I would expect the command to have an --all argument which gives the user the possibility to reset all passwords of all users at once.

Of cause this is possible to combine the wp user list with the wp user reset-password command achieve the same result. But since many other commands have an --all argument I would expect to have it available for the wp user reset-password command, too.
