hypervisor: Introduce hypervisor crate

The purpose of this trait is to add support for other hypervisors than
KVM, like e.g. Microsoft Hyper-V.

Further commits will define additional hypervisor related traits like
Vcpu and Vm. Each of the supported hypervisor will need to implement all
traits defined from the hypervisor crate.
