Improve User experience

This patch adds access to new REST API for config and service
metadata retrieval.

The following work has been done:

* Create new manager for config retrieval
* Create new Resource and CRUD manager for service info retrieval
* Add managers to client
* Add new CLI command and openstack client entries
