Add support for UserContextData property for InitiateAuthRequest

[mgamsjager]

Describe the feature

To pass on the real client user IP address. Cognito uses the EventContextDataType (https://docs.aws.amazon.com/sdkfornet/v3/apidocs/items/CognitoIdentityProvider/TEventContextDataType.html) in the InitiateAuthRequest for this

See example https://docs.aws.amazon.com/sdkfornet/v3/apidocs/items/CognitoIdentityProvider/TInitiateAuthRequest.html

var response = client.InitiateAuth(new InitiateAuthRequest 
{
.....
    UserContextData = new UserContextDataType {
        EncodedData = "AmazonCognitoAdvancedSecurityData_object",
        IpAddress = "192.0.2.1"
    }
}

It would be nice to have the option to provide the UserContextData object to the request

Use Case

Make use of the new Cognito plans. These only work correctly if we can pass on the real users IP address

Proposed Solution

Add/up method to add the UserContextData object to the InitiateAuthRequest

Other Information

No response

Valid feature request for adding support for UserContextData while using InitiateAuthRequest flow. Perhaps, we should also scan all APIs that this HLL uses that support UserContextDataType.
