Simple Cmdline User-Creation Tool

[Nebukadneza]

Hi,

since #272 (User Administration) is a big of a bigger hunk and will need some time, I propose an intermediate step, which will already help users hosting closed instances: A simple commandline user creation/deletion script.

Currently users hosting a closed instance need to manually hash passwords using scrypt on the node commandline, and enter user-data into their respective database. AFAIK no database-commandline or frontend has scrypt-kdf functionality builtin, so this is quite labour-intensive.

A simple Commandline tool that does something like:

node user_admin.js
    Usage: node user_admin.js <-a||-d> [-p <password>] <user email>
        -a Add User
        -d Delete User
        -p Use password from commandline (rather than prompting)

Would lighten the work of administrators of such a instance tremendously. At the same time, it should be quite simple and quick to implement, so that it can be available quickly.

I could try to understand your database backend and how to argparse in node, and implement/PR a functionality like that. Please let me know what you think about the idea.

Best,
-Dario

Actually you should be fine with making a require on the User model.

To create such a tool you basically refactor this code by replacing all web request content with CLI and add a function to replace the password:
