Write plugin reference chapter

[lacasseio]

The chapter focuses on what the plugin adds/do to the project and not explaining what each problems it tries to solve. It should link to samples that demonstrate the feature in action. Here is a general plan:

• Description: brief explanation and compatibility with core Gradle plugins
• Usage: mention the plugin work as settings and project.
• Features: a table with each features, gradle property to enable and default (enabled/disabled)
• A section for each feature that contains the plugin version introduced as well as mutation to the Project and or Settings
• Where it makes sense, include compatibility matrix, core plugins and Gradle version. Some features are present to backport a fix on older Gradle.
