Inject user preferences into the environment

[ciyer]

Description

Users want to be able to set up an environment configuration that moves with them. Examples of what may be in here include:

• .bashrc
• Jupyter font sizes

Solution

Add code to the docker entrypoint that looks for a repo in gitlab that conforms to a naming convention which includes the user's name. If it is found, copy over and append the configuration files into the environment.

Document the process in the renku documentation.

Should we agree on a repo name that will be used for this? That would be easiest. @emmjab @cchoirat any thoughts?
