Take AWS options from appsettings

This is a nice little library, but one issue that I’m having is that it doesnt take AWS options from appsettings. What are your thoughts on supporting this?

For example, if I have the following in my appsettings file, I’d want this information to be used when creating the Secrets Manager client:

{
    "AWS": {
        "Region": "eu-west-1",
        "Profile": "dev",
    }
}

At the moment, it only seems to use the information in the credentials file, or if the AWS_PROFILE or AWS_REGION environment variable are present, it’ll use the information from there.

The AWS .NET Configuration Extension for Systems Manager has an AddSystemsManager method which builds the IConfigurationBuilder and fetches the AWSOptions from it by IConfiguration.GetAWSOptions(), which allows these options to come from appsettings. I’m wondering if it would be possible to support something similar in this library.

@devklick thanks for your effort. Usually when I have to test stuff that uses Microsoft.Extensions.Configuration and Microsoft.Extensions.DependencyInjection I end up using the concrete types rather than mocking the interfaces. I am aware it pushes towards integration tests but I prefer that to having complicated but “pure” unit tests.

When it comes to Configuration, I rely on the in-memory provider or the AddObject library I have here.

As for your work in progress, would you mind pushing your branch as a draft PR?
