Fluss version

0.7.0 (latest release)

Please describe the bug 🐞

Currently, when we put fluss connector into flink lib, the job preforms well. When I run with "--jar" or "add jar", the sql-client will fail with :

ERROR] Could not execute SQL statement. Reason:
com.alibaba.fluss.metadata.ValidationException: No plugin for the protocol 'sasl' is found in the classpath

It's because when sql gateway run(in flink 1.20), the thread classloader is not the user classloader. Thus, though user classloader can loaded flink-fluss-1.20.jar, but the thread classloader cannot do it.
