RFR: JDK-8212780: JEP 343: Packaging Tool Implementation

[Andy Herrick]

This patch implements the Java Packager Tool (jpackager) as described in 
JEP 343: Packaging Tool <https://bugs.openjdk.java.net/browse/JDK-8200758>

jpackager is a simple packaging tool, based on the JavaFX |javapackager| 
tool, that:

  * Supports native packaging formats to give the end user a natural
    installation experience. These formats include |msi| and |exe| on
    Windows, |pkg| and |dmg| on MacOS, and |deb| and |rpm| on Linux.
  * Allows launch-time parameters to be specified at packaging time.
  * Can be invoked directly, from the command line, or programmatically,
    via the |ToolProvider| API.
