Abhijeet Kaur 92d2981726 contrib bots: Edit code for uniformity.
Add one function (get_bot_botname_response()) that generates response
from the given input and replies back to the handle_message with the final
content of response to be sent. Also add code to bots(except followup) to
reply to private messages along with stream messages.
