Camel Kafka doesn't support SASL_PLAINTEXT security protocol

Issue

I have enabled SASL in Kafka server and I try to configure my consumer endpoint like :

<route id="KafkaConsumerRoute">
    <from uri="kafka:localhost:9092?topic=test&amp;groupId=testgroup&amp;keyDeserializer=org.apache.kafka.common.serialization.StringDeserializer&amp;valueDeserializer=org.apache.kafka.common.serialization.StringDeserializer&amp;securityProtocol=SASL_PLAINTEXT"/>
    <log message="The message contains ${body}"/>
    <to uri="mock:result"/>
</route>

We would need this for our application to authenticate the consumers based on username and password.
