Expose sasl.jaas.config to support multiple JAAS configs in a single JVM

[gquintana]

Since Kafka Client 0.10.2.1, Kafka consumer has a new setting called sasl.jaas.config which allows:

• having different login/password per Kafka consumer
• not setting the system property in https://github.com/logstash-plugins/logstash-input-kafka/blob/v6.3.0/lib/logstash/inputs/kafka.rb#L343 is not necessary anymore
• not placing login/password in a specific JAAS config file

See
http://kafka.apache.org/documentation/#security_sasl_plain_clientconfig

• Version: 6.3

This is required to support kafka environments like IBM Message Hub - see https://stackoverflow.com/questions/46629331/unrecoverable-error-with-kafka-input-plugin-connecting-to-ibm-message-hub/46640611#46640611

+1 ... Is there any plan to implement it? It is really must have feature for us, we have many troubles caused by not supporting this in plugin.
