Create a ModelNode to CLI call transformation facility

Add a transformation function that can convert a ModelNode representation of an operation into a CLI low level operation. In the case of a composite operation, this should result in a CLI batch command with multiple CLI low level operations.

This capability involves introducing a transformation API (ModelNodeTransformer?), and perhaps an SPI to support pluggable transformation algorithms.

Future transformations might be:

• Java code - Transformation of a ModelNode based management operation into Java code using the jboss-dmr API to build a ModelNode and use the ModelController client API
• Python code - Transformation of a ModelNode based management operation into Python code that builds a JSON representation of the model node and some demo code calling an HTTP API in python to make the invocation
• Curl code - Transformation of a ModelNode based management operation into a curl statement(s) that can be cut and paste into a console
• XHR JS code - Transformation of a ModelNode based management operation into JS XHR calls

This functionality belongs in a new library, and once completed should be directly ported to HAL(console) as a prototype (this would enable HAL to record and display operations, CLI calls, or even code of the work performance based on user selection)
