Description

In a sequence like this:

tEnv.getConfig().setIdleStateRetentionTime(minRetention, maxRetention);
Table table = tEnv.fromDataStream(elements);
tEnv.toAppendStream(table, Row.class);

the call to toAppendStream will override the value set in tEnv.getConfig.setIdleStateRetentionTime. I think we should change that behavior, as we want to drop the version with explicit QueryConfig and recommend the described setup.

Thanks hequn8128 for pointing it out.
