Description

According to further discussions in ML and FLIP-50, we will create a new backend instead of modifying the existing HeapKeyedStateBackend, to prevent any surprise for existing in-production usage (and only change the spill-able one to default in future if proven to be stable).

This JIRA aims at creating a sub-module under the flink-state-backends module for the spill-able heap backend.
