[IMP] IoT : Automatic registration of the IoT Box in HTTPS without certificate

When we are on HTTPS and we want to connect a box with the scan
we need to accept manually the certificate of the box.
With this commit we don't need to accept manually the certificate.
We don't have problem of mixed content if we use the onload method of Image object
So we load a image and put on parameter the token of the odoo DB to make a connection.
