Create a new base REST API interface

* restapi module provides basic REST API support
  * uses dicts rather than Resource classes
  * JSON serialization/deserialization
  * log requests in 'curl' format
  * basic API boilerplate for create/delete/list/set/show verbs
* ignore H302 due to urllib import
