C# Class KafkaNet.KafkaMetadataProvider

This provider blocks while it attempts to get the MetaData configuration of the Kafka servers. If any retry errors occurs it will continue to block the downstream call and then repeatedly query kafka until the retry errors subside. This repeat call happens in a backoff manner, which each subsequent call waiting longer before a requery.
