c48d0c1a67 hypervisor: kvm: Implement vCPU state method
Implement the vCPU state getter and setter separately from the initial
KVM Hypervisor trait implementation, mostly for readability purposes.

72e39a3496 hypervisor: Add KVM implementation
For each of the traits we are defining kvm related structures
and add the trait implementation to the structs. For more information
please see the kvm-ioctls and kvm-bindings crate.

This is a standalone implementation that does not include the switch of
the Cloud-Hypervisor vmm and arch crates to it.

683210d6e9 hypervisor: Add Hypervisor trait
As the only hypervisor that Cloud-Hypervisor supports is KVM, the
Hypervisor trait accomodates for the upcoming KVM implementation.

This trait will be instanciated at build time through hypervisor
specific features, i.e. it's not aiming at run-time selection of
hypervisors for Cloud-Hypervisor.

f5afc288d8 hypervisor: Add Vm trait
This VM trait should be implemented by each underlying hypervisor.

Previously created hypervisor object should create the VM based on
already selected hypervisor. This is just the trait definition. For each
of supported hypervisor we need to implement the trait. Later we will
implement this trait for KVM and then Microsoft Hyper-V.

f9b51a41b5 hypervisor: Add Vcpu trait
This Vcpu trait should be implemented by each underlying hypervisor.

Previously created hypervisor object should create the VM based on
already selected hypervisor and Vm object should create this vcpu
object based on same hyperviosr. Each of this object should be
referenced by trait object i.e <dyn Vcpu>.

56a1638517 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.
