Config: need to support turning on DEBUG logging via CLI or configuration file

[Aaronontheweb]

In order to see diagnostic output such as #353 we really need to have a way to allow end-users to change the ILogger verbosity via the CLI.

Lol looks like we already support this, at least per the documented CLI args:

  --verbose             Optional. (Default: false) Enable debug logging.

Let's see if that's actually effective though:

Incrementalist/src/Incrementalist.Cmd/Program.cs

Lines 80 to 84 in 83f5bfc

	var loggerFactory = LoggerFactory.Create(builder =>
	{
	builder.SetMinimumLevel(options.Verbose ? LogLevel.Debug : LogLevel.Information)
	.AddConsole(loggerOptions => { });
	});

Yes it is! Nevermind.
