[REEF-1942] Add ability for .NET Client to wait for Driver to complete.

  * Added `IJobSubmissionResult.WaitForDriverToFinish()` which blocks
    until the Driver is done. This uses a new HTTP handler on the Java
    side of the Driver.
  * Added `DriverStatusHTTPHandler` to REEF / Java to query the Driver's
    status via HTTP and added that Handler to the Driver Configuration
    used by REEF.NET.
  * Added a call to block at the end of HelloREEF.

This change also adds a bunch of infrastructure to make this more
informative in the future, e.g. `DriverStatus` in .NET. To keep this
focused, I did not expose that machinery.
