add simple user through HTTP request

[ghost]

Hi, first of all nice work ! I use it a lot.

I don't manage to create (sign up) some new users by HTTP requests add_new_user(username, password, email) Do you think it would be possible ?

For now I create a lot of admin users (by adding a lot of admin users in the doccano/tools/run.sh). But I don't like this way.

Have a nice day !
