feat(schematics) logger generation schematic

[NachoVazquez]

The Problem

Custom Loggers are the recommended way of creating logs with Lumberjack, however creating custom Loggers requires a bit of boilerplate.

The Goal

Create schematics generators to create the Custom Loggers boilerplate for us.

Tasks

• Generate logger extending LumberjackLogger
• Generate logger extending ScopedLumberjackLogger (--scope=<scope-property-value>)
