Add a plugin to generate fields information.

Problem/Motivation

Currently, the module only shows 'Available Field' text, instead of showing the actual field labels associated with the content type. We can add a new plugin that will show information related to fields or modify the existing ones.

Steps to reproduce

Check the documentation overview page or generate the documentation in word plugin.

Proposed resolution

Write new/modify existing plugin to add this improvement feature.

Remaining tasks

User interface changes

API changes

Data model changes
