[frontend] Dev mode without password

[frodrigo]

I think we can easily make a frontend without password. cc @jocelynj
The items doesn't not need to be create in order to send it from the backend.

The issue with not using a password is that the database for frontend is osmose_frontend, which is not the same name than the user name. With default postgresql configuration, this requires to connect via localhost, and a password.

It might be possible to allow access through postgresql socket from user osmose to database osmose_frontend, but I don't know exactly how.

I talk about upload result without password, not about db.

[jocelynj]

I don't see way to upload results without password, at least not without modifying frontend code or using some internal scripts.

@frodrigo @jocelynj thank you for the review and the issues. I can't work on this for the moment, but I'll check it all next month.
For this issue, the actual workaround is too simple and limited, I'll try to find a better one.
