Secret Parameter Plugin for Smith

This takes ServiceBindings or explicit Secret dependencies, and converts them into a form acceptable to parametersFrom in Service Catalog.

e.g. a ServiceBinding with a smith resource name of my-binding produces a secret like so:

Secret:
  myVar: x

And with a plugin spec of:

plugin:
  spec:
    mapping:
      my-binding: # <-- name of Smith resource
        myVar: myComputeInputVar

we end up with:

Secret: my-binding: > {"myComputeInputVar": "x"}

This plugin will error out if the mapping is not possible in any way (i.e. there is no my-binding amongst the dependencies, OR there is no myVar in the secret generated by my-binding).

For a slightly more real example, see the examples directory.
