## What changes were proposed in this pull request? It adds Kafka delegation token support for DStreams. Please be aware as Kafka native sink is not available for DStreams this PR contains delegation token usage only on consumer side. What this PR contains: * Usage of token through dynamic JAAS configuration * `KafkaConfigUpdater` moved to `kafka-0-10-token-provider` * `KafkaSecurityHelper` functionality moved into `KafkaTokenUtil` * Documentation ## How was this patch tested? Existing unit tests + on cluster. Long running Kafka to file tests on 4 node cluster with randomly thrown artificial exceptions. Test scenario: * 4 node cluster * Yarn * Kafka broker version 2.1.0 * security.protocol = SASL_SSL * sasl.mechanism = SCRAM-SHA-512 Kafka broker settings: * delegation.token.expiry.time.ms=600000 (10 min) * delegation.token.max.lifetime.ms=1200000 (20 min) * delegation.token.expiry.check.interval.ms=300000 (5 min) After each 7.5 minutes new delegation token obtained from Kafka broker (10 min * 0.75). When token expired after 10 minutes (Spark obtains new one and doesn't renew the old), the brokers expiring thread comes after each 5 minutes (invalidates expired tokens) and artificial exception has been thrown inside the Spark application (such case Spark closes connection), then the latest delegation token picked up correctly. cd docs/ SKIP_API=1 jekyll build Manual webpage check.
