Build full DslLoader code into knife plugin #280

The current Gorillib::Resolve code needs to be replaced with a more flexible framework. The operating principle is to collect the ordered assertions made in a DSL file, and allow them to be filtered. Doing so allows arbitrary reordering of the assertions, in ways that allow resolution based on statement order, rather than the more complicated implicit rules of Resolve.

This has been tested simply, and should work in the majority of existing clusters.

Use https://github.com/a2design-company/json-compare to compare the results of this and Gorillib::Resolve process, across a number of cluster definitions. Also consider a stronger set of spec tests (in particular, test that locally declared variables are available for later usage, rather than lost in the sea of context).
