Provide REST extensions to Nuxeo Automation

Automation is more a RPC system than a Rest binding.

It does actually use JAXRS, but the Rest resource is the Operation it-self :

• calling GET will give you the definition
• calling POST will execute it

Having a simple RESTful CRUD API would help :

• simple testing
• integration with Javascript MVC model

The goal if this task is to build a CRUD RESTful API on Document and adapter.

Here we are talking about reverting the Automation paradigm :

• the Resource if the document and not the Operation
• the Operation is the Http Verb and is limited to CRUD

We could build that as an extension of the existing Automation.

This basically means that Automation exposes 3 endpoints :

• Operation RPC endpoint (/site/automation/${operationId})
• Operation RPC batch endpoint (/site/automation/batch)
• RESTFull/CRUD

This new CRUD API should focus on CRUD on a DocumentModel or it's adapter.
On the contrary to Operations, CRUD API can not be combined inside an AutomationChain and don't need to appear inside Studio.

Target url pattern could be :

• for pure CRUD : GET / PUT / POST / DELETE on

      /site/automation/nxdoc/{repo}/{uuid}©{adapter}
  

• for execute an operation on the target doc : GET or POST on

      /site/automation/nxdoc/{repo}/{uuid}/{operation}@{adapter}
