[FLINK-3460] [build] Set Flink dependencies in flink-streaming-connectors, flink-batch-connectors, cep, gelly and flink-ml modules to provided

The flink-streaming-connectors all depend on flink-streaming-java in compile scope.
This entails that this dependency is always pulled in, when you build a fat jar. By
setting this dependency to provided, this will be avoided. Furthermore, the connectors
are always used in conjunction with flink-streaming-java. This means that you will
always have an explicit dependency import of flink-streaming-java in your build script.
This allows you to run your program locally but it is also easy to exclude the dependency
from being included in the fat jar by setting it to provided, as well.

This closes #1683.

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.

- Clean dependencies in flink-streaming connectors

Users using CDH4 can now build Flink against Hadoop 2.0.0-alpha.

- 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.

- remove usages of commons-lang (we use only commons-lang3, as defined in flink-runtime/pom.xml)
- Upgrade maven failsafe to 2.17 so that tests also fail if the test errors (exceptions during execution)
- added new build profile "docs-and-source" that creates javadocs and source attachments. These are usually only needed when releasing (--> speed up the build)

- 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.

When trying to use packages that use stratosphere-tests in
stratosphere-examples you used to get a circular dependency. Now
packages can use the testing utilities without pulling in all the
transitive dependencies of stratosphere-tests.

It contains code maintained by the project. (Most of them have a lot of dependencies and are not required by most users)
Move pact-array-datamodel to stratosphere-addons
Move pact-hbase to stratosphere-addons

End the version name craziness and go back to have 0.4-SNAPSHOT as
version number. Also change the name of the toplevel pom back to
stratosphere.
