ENH: Temporary HOME directory for scripts

Created by: Quazgar

The server should create temporary home directory for scripts and set the HOME environment variable accordingly.

Advantages

This is necessary for running scripts with reduced privileges.
Scripts may modify their home directory in a non-persistent way.
In the future, different scripts may come with different pre-configured environments.
