OpenNebula

When using the "to_hash" function in the ruby OCA Library it will can different datatypes which will require addtional coding to handle. If a VM has multiple disks for nics it will make an Array, if not it just creates a string. Providing a common and predictable datatype is the goal.

Below is a patch which will always return an Array datatype for NIC and DISK attributes when using the to_hash method.
