Summary: Reuse StateNamespace.stringKey in Flink States

Issue Type: Improvement
Components: runner-flink
Reporter: Jingsong Lee
Assignee: Jingsong Lee
See BEAM-1587
StateNamespace.stringKey did two things: the base64 encoding of window , and
then String.format. These two things consumption is not small. We can cache it
in State and reuse.
Further more, we can cache the state.
