Description

Adds overloaded methods for response builder withSpeech and withReprompt to allow PlayBehavior to be set.

Motivation and Context

PlayBehavior attribute on Alexa Response provides a way to interrupt Alexa speech, which is useful during some skill development like game skills. Since Response Builder is the SDK's way of generating the response, we need to provide a way to add this attribute on the speak and ask commands of the builder, for skill developers to use.
