Feature: add user to /etc/passwd file

[arnaud-deprez]

Describe the bug

Java needs to resolve user id to set java.user and java.home properties properly but it is currently set to ?.
Nodejs also use that for global npm tool installation.

It leads to strange behavior for a lot of libraries that rely on it.

Expected behavior

Even if in openshift the user id is randomly generated, it should look as a regular user for all libraries that require it.
