create functionality: display events generation 1

[essare-rimaz]

bot should know how to answer inputs such as

• are there some events happening today
• is there some party in prague
• where can i find list of events

nlu

create intent with at least 5-10 examples

utter

create an answer for the intent with a link to linktree

rule

link the intent and the reaction utter

domain

create a new domain file that will list nlu and utter

this one would partially overlap with trip_tips intent (however, trip_tips does not include esn events, only general events in prague or czech republic)
