Guy Kim 5c841f2d7b Refactoring ITRI DISCO cinder volume driver
This commit is the refactored version of DISCO volume driver of ITRI.

We change the SOAP API to REST API. It adds also two different classes:

* Class for the different calls using REST API
* Class for attach/detach a DISCO volume

It also includes the unit tests.
