This namespace defines methods for publishing data to
 Kafka topics. The methods defined here are essentially wrapper
 around variants of `send` methods defined in
 `org.apache.kafka.clients.producer.KafkaProducer`.

 At the time of initialization, an instance of
 `org.apache.kafka.clients.producer.KafkaProducer`
 is constructed using config values provided in `resources/config.edn`.

 A producer can be configured for each of the stream-routes
 in config.edn. Please see the example below

 `
   :stream-router {:default {:application-id "test"

                             :bootstrap-servers    "localhost:9092"

                             :stream-threads-count [1 :int]

                             :origin-topic         "topic"

                             :proto-class          "flatland.protobuf.test.Example$Photo"

                             :channels             {:channel-1 {:worker-count [10 :int]
:retry {:count [5 :int]
:enabled [true :bool]}}}

                             :producer             {:bootstrap-servers "localhost:9092"

                                                    :acks "all"

                                                    :retries-config  5

                                                    :max-in-flight-requests-per-connection 5

                                                    :enable-idempotence  false

                                                    :value-serializer  "org.apache.kafka.common.serialization.StringSerializer"

                                                    :key-serializer    "org.apache.kafka.common.serialization.StringSerializer"}}

 Usage:

 `
    Please see `send` for publishing data via Kafka producers
 `

 These are the KafkaProducer configs currenlty supported in Ziggurat.
 - bootstrap.servers
 - acks
 - retries
 - key.serializer
 - value.serializer
 - max.in.flight.requests.per.connection
 - enable.idempotencecd

 Please see [Producer configs](http://kafka.apache.org/documentation.html#producerconfigs)
 for a complete list of all producer configs available in Kafka.

Sentry reporting functions used by both Ziggurat and the actor.
