0.10-SNAPSHOT continues on branch release-0.10

This reverts commit f8e12b20.

The commit had to be reverted because the RowSerializer is not in sync
with other comperators and serializers. See FLINK-2236.

Closes #851

This closes #831

This greatly reduces compile time while still supporting the same
feature set.

Package name is now flink-table. ExpressionOperation is renamed to
Table.

This also adds more JavaDoc and ScalDoc.

This closes #497

This closes #454

  - Move sling JSON dependency to streaming connectors (prev streaming core)
  - Exclude YARN API from transitive mapreduce-core dependencies we use the dependency
    only for .mapred and .mapreduce interfaces
  - Remove some unnecessary dependencies (junit in java8)
  - Manage Kryo dependency
  - Cleanup minor POM warnings.

This closes #275

Removed Disclaimer file
Eliminated unnecessary incubating substrings
Bumped version to 0.9-SNAPSHOT

Fixed JobManagerITCase to properly wait for task managers to deregister their tasks. Replaced the scheduler's execution service with akka's futures. Introduced TestStreamEnvironment to use ForkableFlinkMiniCluster for test execution.

Replacing the EventCollector and the MemoryArchivist.

Finished EventCollector and adjusted ExecutionGraph and ExecutionVertex to register actors as listeners.

The performance of data-intensive jobs using Kryo is probably going to be slow.

Set correct classloader

try to use Kryo.copy() with fallback to serialization copy

This closes #159

- Clean dependencies in flink-streaming connectors

[FLINK-1114] Move scala-style checks to scala projects, change paths to style conifg, to allow isolated building of individual projects.

Also actually use termination criterion in TransitivelClosureNaive
Java example.

Add ConnectedComponentsITCase for Scala Example

Also fix some formatting in the example code

Add WebLogAnalysisITCase for Scala Example

Some minor reformatting of example code and scaladoc.

Add ITCases for TriangleEnumeration Scala Examples

Also fix some formatting and make TriangleEnumerationOpt Scala produce the
same output as the Java version.

Add PageRankITCase for Scala Example

Also fix formatting in PageRank Scala Example.

Fix formatting in EnumTriangles Scala Examples

Remove Old/Deprecated Scala Examples and ITCases

Fix formatting in EnumTrianglesBasic.scala

Fix formatting in LinearRegression Scala Example

Remove old Scala LineRank Code and RelQuery Example

[scala] Fix typo in scaladoc in GroupedDataSet

[scala] Fix Scaladoc of Join and CoGroup Operation

Was still referring to the type of join/coGroup function that returns an
Option.

Fix tab vs. spaces in flink-scala and flink-scala-examples

Don't bother looking at the diff, this is almost a complete rewrite of
the previous Scala API. This uses all the work put into the Java API,
such as TypeInformation, the serializers and comparators and the
operators.

The Scala DataSet and ExecutionEnvironment wrap their respective Java
equivalents. TypeInformation is generated by a macro that uses
TypeInformationGen and other macro support classes. The Java
TypeExtractor is completely bypassed but the TypeInformation and
sub-classes are created by the Scala type analyzer. There is special
support for Scala Tuples in the form of ScalaTupleTypeInfo,
ScalaTupleSerializer, and ScalaTupleComparator.

This also adds tests to flink-scala that are ports of the tests in
flink-java.

There are not yet any Scala specific tests in flink-tests. All the
scala example ITCases are commented out, as well as the examples
themselves. Those will be uncommented once the examples are ported. This
will happen in separate commits.

- update _config.yaml of integrated documentation
- quick check on the quickstarts / build instructions to match the latest release
- quickstart.sh scrips now point to the correct versions.

- Upgraded to junit 4.11 and fixed code that used deprecated
- Changed scala dependency from 2.10.3 to 2.10.4 to avoid conflicts with scalatest dependency
- Upgraded log4j and commons-logging dependency
- Removed superfluous dependency on commons-codec
- Upgraded dependency versions in the base module
- Ensured consistency of avro versions across submodules
- Upgraded AWS dependency to version 1.8.1
- Unified configuration of jetty dependency

This closes #80.

This closes #33.
