[FEAT] Execute command after upgrading docker image

[dieterlind]

Is this a new feature request?

• I have searched the existing issues

Wanted change

After upgrading the docker imager I have to issue a command to make my sundtek dvb-card work again (running on synology NAS).
This is somehow annoying.
So it would be good to have a parameter (??) or similar to hand over a path to a script executed on restart after docker image update

Reason for change

Reducing manual effort after updating

Proposed code change
