Load images from an https server

[cammellos]

For performance reasons, we should load images from an https server run locally, instead of passing them through the bridge.

The issue is to automate the creation on certificates and making sure that they are trusted.

On IOS we can follow:

while on Android we could use https://stackoverflow.com/a/57046889/13685841 , but it might require changing fast-image library.

The status-go PR is here status-im/status-go#2418 , I can update it to use SSL, @flexsurfer has done already some work here https://github.com/status-im/status-react/pull/12780/files (changing in the frontend are minimal, other than accepting the certificate).
