Initialize `Waterdrop`
Waterdrop is a kafka producer library for ruby
https://github.com/karafka/waterdrop
Since our service is only producing events Waterdrop
seems to be the easiest solution to get started.
The waterdrop.rb
initializer starts a connection to the bootstrap server.
From here onwards we can simply call
$producer.produce_async(topic: 'events', payload: { 'hello' => 'worlds' }.to_json)
