0.10-SNAPSHOT continues on branch release-0.10

Closes #851

This closes #189

With this change, users can submit a Flink job to a YARN cluster without having a local client monitoring the Application Master or job. You can basically fire and forget a Flink job to YARN.
For supporting this, the ApplicationMaster can now monitor the status of a job and shutdown itself once it is in a terminal state.

The change also verifies that various ways of setting the parallelism on YARN are passed through the system correctly (per job, session).

There was a bug in YARN container creation which made the configuration values for the heap offset useless. This change fixes this error.

All mentioned features and bugs are covered by the flink-yarn-tests.

This closes #542

This closes #454

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

Replacing the EventCollector and the MemoryArchivist.

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

- 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)

source should now build without the presence of a .git directory
included the quickstart-archetypes into the main project.
