[FLINK-4717] Add CancelJobWithSavepoint
This builds on top of #2608.
- Adds CancelJobWithSavepoint message, which triggers a savepoint before
cancelling the respective job. The periodic checkpoint scheduler is stopped
before doing this so that no checkpoints happen between the savepoint and
cancellation. Note that users could manually trigger another savepoint while
cancel-with-savepoint happens, but I think this is tolerable.
- Adds `-s [targetDirectory]` option to CLI cancel command:
* Regular cancelling:`bin/flink cancel <jobID>`
* Cancel with savepoint to default dir: `bin/flink cancel -s <jobID>`
* Cancel with savepoint to target dir: `bin/flink cancel -s [targetDir]
<jobID>`

> Naive version of atomic stop signal with savepoint

> Key: FLINK-4717
> URL: https://issues.apache.org/jira/browse/FLINK-4717
> Project: Flink
> Issue Type: New Feature
> Components: State Backends, Checkpointing
> Affects Versions: 1.2.0
> Reporter: Till Rohrmann
> Priority: Minor
> Fix For: 1.2.0
>
>
> As a first step towards atomic stopping with savepoints we should implement a
> cancel command which prior to cancelling takes a savepoint. Additionally, it
> should turn off the periodic checkpointing so that there won't be checkpoints
> executed between the savepoint and the cancel command.
