    [FLINK-8945] [kinesis] Allow customization of KinesisProxy

    ## What is the purpose of the change
    Allow customization of KinesisProxy. In this case we want to override just the getShardList
implementation to use ListShards instead of DescribeStreams.
    ## Brief change log
      - Changed the constructor from private to protected for KinesisProxy
    ## Verifying this change
    This change is a trivial rework / code cleanup without any test coverage.
    Also verified with mvn clean verify. 
      - *Added integration tests for end-to-end deployment with large payloads (100MB)*
      - *Extended integration test for recovery after master (JobManager) failure*
      - *Added test that validates that TaskInfo is transferred only once across recoveries*
      - *Manually verified the change by running a 4 node cluser with 2 JobManagers and 4
TaskManagers, a stateful streaming program, and killing one JobManager and two TaskManagers
during the execution, verifying that recovery happens correctly.*
