[Improvement] Remove redundant Thread.sleep wherever possible

[yuqi1129]

What would you like to be improved?

We used the following code pattern to wait for the resource that haven't be ready

while( xxxx) {
  xxxxx
  Thread.sleep(xxx);
}

I think we can remove these code patterns as many as possible and use awaitility instead. for please please refer to

    Awaitility.await()
        .atMost(MAX_WAIT_IN_SECONDS, TimeUnit.SECONDS)
        .pollInterval(WAIT_INTERVAL_IN_SECONDS, TimeUnit.SECONDS)
        .untilAsserted(
            () ->
                ITUtils.assertColumn(
                    Column.of(DORIS_COL_NAME3, Types.VarCharType.of(255), "col_3_comment"),
                    tableCatalog.loadTable(tableIdentifier).columns()[2]));

How should we improve?
