[hotfix] Remove 'ByteArrayInputView' and replace deserialization in TypeInformationSerializationSchema with more efficient reusable buffers.

The methods snapshotState and notifyCheckpointComplete are always
mutually exclusive. The RMQSource relies on this but the test makes a
false assumption when it calls those two methods at the same time.

This closes #1569.

This reverts commit 6b01a890. The
introduced locks are not necessary. The checkpointing test case only
needs to be adapted to the checkpointing runtime behavior.

The auto-magic for Joda Time was limited to very few classes. It was intransparent what
cases would be handled.

Adds message passing between Hadoop's async resource manager client and
the YarnJobManager actor.

This closes #1561.

This is needed for streaming library features, is identical to the batch API.

Henceforth, we shall only use the term lower in the context of timestamps
to denote that an event has occurred before another event.

Before, the user-specified StateBackedn would not be set when generating the
JobGraph if checkpointing was disabled.

This keeps the log cleaner in case of failed timers while canceling tasks.

Several packages had been updated locally by users when compiling the templates
without changing the version in bower.json. The following packages have been
explicitly updated.

 jquery              2.1.4  →   2.2.0
 angular            1.3.15  →   1.4.8
 angular-moment      0.9.2  →  0.10.3
 angular-ui-router  0.2.13  →  0.2.15
 bootstrap           3.3.5  →   3.3.6
 d3                  3.5.5  →  3.5.12
 dagre-d3           0.4.10  →  0.4.11
 font-awesome        4.3.0  →   4.5.0

This closes #1525

-parallelism is stored Value object within the OperationInfo, so it can be passed as a reference to multiple operations (in cases where a set is internally executed as multiple operations)
-setParallelism is called for every DataSet with either a user-set value or env.getParallelism
-added a DataSink set, providing access to name() and setParallelism() for sinks

This closes #1465.

-identifier saved in java OpInfo
-changed default values to prevent null exceptions
-all operations use the same routine to transfer parameters
-PyPlRcv can handle Tuple0
-labeled py OpInfo fields as transferred/internal
-fixed broadcast OpInfo not having correct identifier
-removed unused projection code

[FLINK-3258] [runtime, streaming-java, tests] Move registerInputOutput code to invoke and remove registerInputOutput

This closes #1538

Before, it could happen that a Task is canceled during snapshotting.
Some State Backends would silently swallow exceptions resulting from
this and the Task would get stuck until the cleanup logic gets to it.

Now, we rethrow a CancelTaskException if isRunning is false in
StreamTask after performing snapshots.

This also moves the logic that swallows exceptions in case a task is not
running anymore from StreamTask to the async caller in Task.

- add suffixes
- adapt change-scala-version script
