Description: 
*Goal:*

To make the following code examples work in production, which is very handy for 
users to set a couple of configurations: 
{code:java}
// instantiate table environment
TableEnvironment tEnv = ...tEnv.getConfig()// access high-level 
configuration
  .getConfiguration()   // set low-level key-value options
  .setString("table.exec.mini-batch.enabled", "true")  // enable mini-batch 
optimization
  .setString("table.exec.mini-batch.allow-latency", "5 s") // use 5 seconds to 
buffer input records
  .setString("table.exec.mini-batch.size", "5000"); // the maximum number of 
records can be buffered by each aggregate operator task
{code}
 

*Suggestion:*

Currently, the return type of `setXXX` method is "void", we can make it return 
`Configuration` itself to support method chaining.
