SAMZA-2074: Read configuration from coordinator stream in checkpoint tool.
Currently, each run of a `CheckpointTool` requires the `TaskModel` from
the `JobModel` for updating the checkpoints. `JobModel` generation involves
reading the `SystemStreamMetadata`, `SystemStreamPartitionMetadata` of the
input streams of the job. Post samza 1.0, this would require the entire
configuration bag stored in coordinator stream.
As a followup to `SAMZA-2059`, this PR changes the `CheckpointTool` read
the configuration from the coordinator stream and use it to generate `JobModel`.
