[FIX] hw_drivers: add cron for HTTPS certificate update

Context:
When an HTTPS certificate is delivered, it is valid for ~1 month.
To avoid missing the certificate, a script is automatically ran daily
to check if a new HTTPS certificate is necessary.

On the IoT box, it is added in the native Unix system with this file:
https://github.com/odoo/odoo/blob/16.0/addons/point_of_sale/tools/posbox/overwrite_after_init/etc/cron.daily/odoo

However, prior to this commit, there is nothing equivalent for windows

Note: the HTTPS certificate check is also done automatically when
accessing the homepage.

Before this commit:
After an HTTPS certificate delivery, if we let the IoT server
running non-stop (and without accessing the homepage).
The HTTPS will expire without any automatic renew.

After this commit:
The cron process is handled by the handler Manager

Other note:
- Using native Windows "Scheduled Task" have been proposed at:
odoo#144584
But, was judged too risky from a security point of view
- `sched` library have been discarded as the code is too verbose
- This is unstable for the iot-box. This is the reason for the
initial Windows check on the import. The iot-box does not need
this fix anyway as explained in the context
