AWS CreateVolume call does not check if referenced encryption key actually
exists and returns a valid new AWS EBS volume even though an invalid key
was specified. Later on it removes the EBS silently when its encryption fails.
To work around this buggy behavior we manually check that the key exists
before calling CreateVolume.
