[FLINK-1629][FLINK-1630][FLINK-1547] Add option to start Flink on YARN in a detached mode. YARN container reallocation.

This commit is changing:
[FLINK-1629]: users can now "fire and forget" jobs to YARN or YARN sessions to there. (Detached mode)
[FLINK-1630]: YARN is now reallocating failed YARN containers during the lifetime of a YARN session.
[FLINK-1547]: Users can now specify if they want the ApplicationMaster (= the JobManager = the entire YARN session) to restart on failure, and how often. After the first restart, the session will behave like a detached session. There is now backup of state between the old and the new AM.

The whole resource negotiation process between the RM and the AM has been reworked.
Flink is now much more flexible when requesting new containers and also giving back uneeded containers.

A new test case is testing the container restart. It is also verifying that the web frontend is proplery started,
that the logfile access is possible and
that the configuration values the user specifies when starting the YARN session are visible in the web frontend.

Add parentheses on Exception#getMessage calls from pattern of:

"Initializing the input processing failed" + e.getMessage() == null ? "." : ": " + e.getMessage()

to:

"Initializing the input processing failed" + (e.getMessage() == null ? "." : ": " + e.getMessage())

Extra parentheses needed to make sure ternary operator check on e.getMessage scope call.

1345cbf [Henry Saputra] Fix checking null for Exception#getMessage call from pattern of:

JobManagerStartupTest should not assume user could not create /does-not-exist-no-sir dir.

Sometimes, user that run tests could have write access to root directory so creating /does-not-exist-no-sir is possible,
hence no exception thrown.

Need to construct a Flink test directory under directory specified under "java.io.tmpdir" and change the permission
to not allow create new directory.
