As an editor I want to access Entity Schemas via Lua in order to build templates and Lua modules to work with Entity Schemas.

Problem:
The labels, descriptions, aliases and ShEx code of Entity Schema is not accessibly for Lua modules and templates. We should make it accessible.

Example:
This would be useful to create the equivalent templates to {{P|P123}} and {{Q|Q123}}. Those help immensely in discussions on-wiki.
