Set context class loader to plugin's class loader when creating kafka consumer

[bugmakerrrrrr]

Description

Set context class loader to plugin's class loader when creating kafka consumer to avoid ClassNotFoundException. For example, when configuring SASL authentication in Kafka, the java.base/javax.security.auth.login.LoginContext needs to new a org.apache.kafka.common.security.plain.PlainLoginModule instance, but the class PlainLoginModule is loaded by class loader of KafkaPlugin, so a ClassNotFoundException would be thrown.
