feat(admin-ui): allow users to install Agama Lab community projects from Admin UI

[duttarnab]

Parent issue# JanssenProject/jans#8785

The idea is to bundle the Agama Lab community projects with the Jans.

So immediately after installing the Janssen Server, if the user goes to Admin ->Auth Server->agama, they see a list of agama projects.

All the admin needs to do is provide config for the project they want to use. That is it.
This will reduce a few steps of downloading the project from GitHub and uploading the .gama to the Janssen Server.
Plus, this becomes ready-to-use functionality being available out of the box.
