Cinder test to integration tests was added

* Now integration tests have a check for Cinder.

While Heat is not correctly working with Cinder volumes (bug #1281534).
I think we should turn off Cinder test when using Heat as infrastructure engine for Savanna.
When bug #1281534 will be fixed, we will turn on Cinder test when using Heat as infrastructure engine for Savanna.
