Dynamic Configuration Support

[nboliver-ventureweb]

Configuring complex transforms that may include a large number of child components should be made dynamic, instead of having to reference a JSON metafield.
From what I can tell, the easiest way to do this is to support reference type metafields. This would just mirror the admin API and allow dynamic configuration by simply passing an array of component IDs as a line item property, where the function could then build the configuration by getting prices etc. from referenced component variants on the fly. This would solve most use cases. and make administration / management / custom bundle development a lot more straightforward.
