ARI: Add support for push configuration of dynamic object

This patch adds support for push configuration of dynamic, i.e.,
sorcery, objects in Asterisk. It adds three new REST API calls to the
'asterisk' resource:
 * GET /asterisk/{configClass}/{objectType}/{id}: retrieve the current
   object given its ID. This returns back a list of ConfigTuples, which
   define the fields and their present values that make up the object.
 * PUT /asterisk/{configClass}/{objectType}/{id}: create or update an
   object. A body may be passed with the request that contains fields to
   populate in the object. The same format as what is retrieved using
   the GET operation is used for the body, save that we specify that the
   list of fields to update are contained in the "fields" attribute.
 * DELETE /asterisk/{configClass}/{objectType}/{id}: remove a dynamic
   object from its backing storage.

Note that the success/failure of these operations is somewhat
configuration dependent, i.e., you must be using a sorcery wizard that
supports the operation in question. If a sorcery wizard does not support
the create or delete mechanisms, then the REST API call will fail with a
403 forbidden.
