Provide a way to remove multiple users at the same time

[llaske]

Currently if an admin want to remove a bunch of users, he has no choice to remove them one by one using the dashboard. It could be a very long process if the number of users is large.
I suggest to add a way, for example using a specific syntax in the import script, to remove multiple users at the same time.

Can we add something like: node scripts/remove_users.js filename.csv? The CSV will contain the name of the users the admin wants to delete.
It'll generate an output file with info about the users deleted/failed to delete.

Will be nice if we could call it from the dashboard. It's why my first thought was to update the import script.

@llaske if you want the bulk delete feature to be accessible from the dashboard then maybe we can modify the Import Users feature on the dashboard such that if we upload a CSV with user type as delete (Current user types are Admin, Student, and Teacher) then the script will find and delete that user.

Sounds like a good idea but we need to update the seed_users.js script to do the same. So admin could do the action both from the command line and from the UI.

Yes. I've already started working on seed_users.js before working on the API. I'll try to make a PR for both the scripts by tomorrow.
