Problem

Currently it's not possible to specify the user inside a container. This is problematic for containers that need to be tested to run as non default user / non root environment. This is also a problem for images that explicitly specify user via USER <name> directive when used in conjuction with WithResourceMapping which copies all files into container as ROOT, preventing their manipulation by the user the container is running under

Solution

Add WithUser(string name)toContainerBuilderthat would map to--user argument ofdocker run`.

Benefit

All proper testing of containers that need to run as non standard user.
