We've had the need several times for a simple node building api - especially in version handlers - to construct relatively simple nodes (couple of nodes, couple of properties) without having to maintain complex bootstrap or properties file, and verbose/long code.

We'll introduce a simple DSL/API similar to the one used to build tasks and deltas for this. Hopefully this will be easy-to-use and follow some of the "fluent" principles.

A starting point was proposed at MAGNOLIA-2828; after some discussion we've adapted it and came up with a slightly different implementation.
