rootless container

[H777K]

Is your feature request related to a problem? Please describe.
In some restricted environments its not allowed to run containers with root privileges. Currently i have to customize and build the docker image by myself, which causes a higher maintaining effort.

Describe the solution you'd like
It would be nice to have the possibilty to run the container with a non root user (e.g. nobody (65534)). Maybe the image can be published with an unprivileged user. For example nginx also provides an nginx-unprivileged image. It would be also fine to have a config, which allows to run the container in an unprivileged mode (if possible).

Describe alternatives you've considered
IMO there are no alternatives: either the possibility is given to run the container as unprivilged user or I have to customize and maintain it by myself.
