Depends on #19 and #61

• [x] Create an endpoint in the niceday-api to get the number of cigarettes from niceday
• [x] Create a method in the NicedayClient
• [x] Create a custom action in rasa for getting the number of cigarettes for a user
• [x] If the user asks 'Hoeveel sigaretten heb ik vandaag gerookt?'. Reply with the number of cigarettes that the user smoked. 'Je hebt vandaag [NUMBER_OF_CIGARETTES] sigaretten gerookt'.
