Review of endpoints to return a single resource

[tdipisa]

Now we are forced to request information from three different endpoints:

• /extjs/resource/{id} for the essential metadata
• /resources/resource/{id}/attributes optionally requested depending by the caller tool on the front-end
• /resources/resource/{id}/permissions optionally requested depending by the caller tool on the front-end

It would be nice to return all the information of payloads returned from the above endpoints through a single request against the extjs endpoint (on the /extjs/resource/{id} endpoint) with the following option as query parameters:

• add parameters includeAttributes
• add includePermissions
