    [FLINK-1529] [jobmanager] Improve error handling on JobManager startup

    This patch improves JobManager startup error behavior, by pulling the heavy initialization
of components (BlobServer, LibraryCache, InstanceManager) out of the JobManager (where construction
is asynchronous in the actor theads).
    
    It also adds more detailed error messages, lets the JobManager process fail in case of
a startup error, and makes test extensions of the JobManager simpler.

> Currently, the JobManager is creates asynchronously (as an actor). If its initialization
fails (for various reasons), the process does not terminate and gives only vague log message
that an actor creation failed.
