Add SSO registration scopes to SSOAWSCredentialsOptions

[aberus]

This adds IList<string> Scopes to SSOAWSCredentialsOptions parsing them from CredentialProfileOptions.SsoRegistrationScopes.

Description

There is currently no way to know if a SSO profile has been set up with sso_registration_scopes when using CredentialProfile.GetAWSCredentials.

Motivation and Context

This change is for a better user experience within the AWS Toolkit for Visual Studio (aws/aws-toolkit-visual-studio#377) and AWS Tools for PowerShell (when using a combination of Get-AWSCredential & Register-SSOOIDCClient cmdlets).

Testing

Create sample config file and run Program.cs file, program should printout sso:account:access

config file:

[profile my-dev-profile]
sso_session = my-sso
sso_account_id = 123456789011
sso_role_name = readOnly
region = us-west-2
output = json

[sso-session my-sso]
sso_region = us-east-1
sso_start_url = https://my-sso-portal.awsapps.com/start
sso_registration_scopes = sso:account:access

Program.cs file:

using Amazon.Runtime.CredentialManagement;

if (new CredentialProfileStoreChain(null).TryGetProfile("test", out CredentialProfile profile))
{
  var creadentail = profile.GetAWSCredentials(profile.CredentialProfileStore) as Amazon.Runtime.SSOAWSCredentials;

  Console.WriteLine(string.Join("\t", creadentail?.Options?.Scopes));
}
