TisonKun updated FLINK-14054:
-----------------------------
    Description: 
Currently enabling checkpointing can only be done via the job code, see the 
following quote from this Flink 
[checkpointing|https://ci.apache.org/projects/flink/flink-docs-release-1.9/dev/stream/state/checkpointing.html#enabling-and-configuring-checkpointing]
 doc:
{quote}By default, checkpointing is disabled. To enable checkpointing, call 
{{enableCheckpointing(n)}} on the {{StreamExecutionEnvironment}}, where _n_ is 
the checkpoint interval in milliseconds.
{quote}
This makes enabling checkingpointing after the job code has been released 
difficult: one has to change and rebuild the job code.

In addition, not only for developer, making checkpointing enabling configurable 
is also of interest for operation teams:
 * They may want to enable checkpointing for production but disable in test 
(e.g., to save storage space)
 * They may want to try out with and without checkpointing to evaluate the 
impact to the job behaviour and performance.  

Therefore, this request.  Thanks.
