• I searched in the issues and found nothing similar.

Motivation

There are many issues caused by as follows:

Error:  com.alibaba.fluss.server.replica.fetcher.ReplicaFetcherITCase  Time elapsed: 616.934 s  <<< FAILURE!
java.lang.AssertionError: Attempt failed.
	at com.alibaba.fluss.testutils.common.CommonTestUtils.retry(CommonTestUtils.java:156)
	at com.alibaba.fluss.server.testutils.FlussClusterExtension.waitUtilAllGatewayHasSameMetadata(FlussClusterExtension.java:361)
	at com.alibaba.fluss.server.testutils.FlussClusterExtension.start(FlussClusterExtension.java:177)
	at com.alibaba.fluss.server.testutils.FlussClusterExtension.beforeAll(FlussClusterExtension.java:123)

the log hides many valuable messages of each test execution, and we can expose them for easier troubleshooting

Solution
