[REEF-1699] Use the {{JAVA_HOME}} notation when starting REEF Evaluators on YARN

   * Use `{{JAVA_HOME}}` instead of locally-issued `.getenv()` call when 
launching REEF Evaluators on YARN
   * Implement a `.toString()` method for better logging

This fix is related to 
[REEF-1665](https://issues.apache.org/jira/browse/REEF-1665) that uses the same 
mechanism to launch the Driver
