Dynamic parameter persistence

[davidlaprade]

Back in the days of Wombat, some endpoints depended on being able to pass parameters back to the system, e.g. a timestamp of the most recently updated item. This was the point behind the #add_parameter method in spree's EndpointBase, which most of the endpoints have as a dependency. Many of them require the #add_parameter method to function properly, for example:

• the shopify endpoint
• the amazon integration
• the ebay integration
• the salesforce integration
• the netsuite integration

to name a few.

This attempts to add this functionality to cangaroo, so that anyone using these endpoints really would find cangaroo to be backwards compatible with Wombat.

Have you guys had a chance to look at this? I've had it running in production for a couple months now without issue. Anything I can do to help keep this moving along?

@bricesanchez it seems ok for me, what do you think?
