OpenCloud Lazy connection and Unit tests

Created OpenCloud Lazy Adapter as a site that uses this, will loose approx 100ms on connections to the OpenCloud.  Also wrote some unit tests which test mocks and discovered some areas of the class that would have thrown PHP fatal errors.  Set the Rackspace/Opencloud revision to 1.6.* for development.  Fixed the Markdown to reflect how to use the Lazy adapters for opencloud.
