Add CommandLineState to the HostBuilder.Properties dictionary

[danielmeza]

Provide access to the CommandLineState throw the Properties on a HostBuilder will allow us to access it in scenarios where there are not DI yet, like in the ConfigureService or ConfigureAppConfiguration methods.

Solution:
Add (

CommandLineUtils/src/Hosting.CommandLine/HostBuilderExtensions.cs

Line 38 in 6e919b6

var state = new CommandLineState(args);

) tot he Properties at HostBuilder like this.

hostBuilder.Properties[typeof(CommandLineState)] = state

We can also create extension methods to get the CommandLineState on the IHostBuild and on HostBuilderContext .
