java.security.auth.login.config required even *_SASL_JAAS_CONFIG variables set [DBZ-1451]

Migrated from [DBZ-1451](https://issues.redhat.com/browse/DBZ-1451)

I got `java.lang.IllegalArgumentException: You must pass java.security.auth.login.config in secure mode.` exception in the debezium starting process even I have all *_SASL_JAAS_CONFIG variables set. Could you explain why this error appears? I use `debezium/connect:0.10` for that
