[REEF-1951] Make Driver Status more robust. This change makes the communication of the Driver status between the Driver and the .NET Client more robust. It gueards against the Client calling the HTTP server to late by changes on the Java side. It guards against calling the HTTP server to early by changes on the .NET side. On the *Java side*, this introduces a new alarm on the clock that makes sure that `DriverStatusHTTPHandler` is called at least once via HTTP in 2s after launching. On the *.NET Side*, this introduces a retry loop around the first attempt to connect to the Driver. This makes sure we don't call it too early. JIRA: [REEF-1951](https://issues.apache.org/jira/browse/REEF-1951) Pull Request: This closes #1413
