Support Max Results for List Handler #334

The ResourceHandlerRequest class does not have a max results field so list handlers need to use the service default or define their own. Would be good to support max results so that consumers of handlers can specify the max results if needed.

For instance, https://docs.aws.amazon.com/cli/latest/reference/ses/list-configuration-sets.html has the field max results. Consumers of the handler may want to be able to specify the max results as well.
