Add VirtualDevice (DeviceComplexType) to BaseMultiObjectComplexType

[stroomdev10]

Will allow modelling of CRUD operations on virtual devices.

I presume VirtualDevice will cover containers (i.e. docker) as well as whole VMs. Also I wonder if it should use its own complex type which is the same as DeviceComplexType but replaces Location with Host (of type DeviceComplexType) to describe the physical host. Or we just add Host to DeviceComplexType to keep things flexible.

Also should we record details of the the virtualisation/containerisation technology (e.g. VMWare, KVM, docker) and maybe the OS somewhere in there.

If it helps, here is an extract of virtualisation out of Linux auditd. It's not designed to address schema changes, but what is on offer from virtualisation services.
