Upgrade python version in TorizonCore with yocto

hi @lucas_a.tx ,
thank you for your answer. I was suspecting something like this.

we are actually considering moving away from docker, as our container is grown too much with all python libraries that we need, in particular Numpy and Scipy and the OTA has become unmanageable.
We are considering putting everything on the TorizonCore filesystem as OSTree pull seems to work better even in case of poor connectivity over the modem (see my post Torizon OTA: constant TLS handshake timeout error)

Regards,
Rocco
