Add Model Configuration template

[garywoodfine]

We have had a request come in via email to add a Model Configuration Template for the database project.

Motivation

The API Template Pack takes an opinionated approach and preference on making use of the Fluent Configuration API to defining Entity Type Configuration and the supporting libraries we've created help simplify this by implementing BaseEntityTypeConfiguration class.

A request came in to simply and automate the creation of these files.

Solution

We are going to create an initial attempt at generating these classes and provide documentation.

Based on feedback gained from this initial release we will work to see how we can improve this.

This is now made available in version 4.0.2 of the API Template Pack
