Update Evaluator config to include application Id and re-connect-to-driver implementation 

for #871

1) application id added to evaluatorconfig
2) re-connect to driver implementation added to context config, which will be set in root context of the evaluator
it's actually a `for` statement:

```java
for (File directory = new File(System.getProperty("user.dir")); directory != null; directory = directory.getParentFile()) {
   // ...
}
```
