Initial Kafka connection should retry

[rtyler]

If 🌭 comes online and receives a message before the Kafka broker is available, it will try to connect, fail, and then never attempt again.

It might make sense to create a Kafka connection object running in its own task that feeds off an internal queue and pushes those messages to Kafka

Upon second thought, I'm thinking that the right path forward would be for 🌭 to not open its syslog socket until a Kafka connection has been established.
