This PR adds 2 new types, which hopefully will help to make the code clearer.
Some of the benefits are that Code-Hex/vz is now only imported in pkg/vf instead of being used directly in multiple places.
The REST code is also simplified.
This is preparation work for #48: the changes in the current PR will be useful for adding the path to the pty device in the REST API.

There should be no user-visible changes after this PR, just internal improvements.

It's only used in the vf package, so it can be renamed to toVzBootloader

All other methods are named toVz() with a lower-case 'z'

The rest/vf package introduces a `VzVirtualMachine` type to wrap virtual
machine interactions. This type is a struct with a
`VzVM *vz.VirtualMachine` member.

This commit makes this struct member anonymous instead of naming it
`VzVM`, this allows to remove the VzVirtualMachine state related methods
which were thin wrappers over methods with (almost) the same name
already defined in `*vz.VirtualMachine`.

This commit renames vzVirtualMachineConfiguration to
VirtualMachineConfig.
vzVirtualMachineConfiguration was a wrapper over the Code-Hex/vz type
vz.VirtualMachineConfiguration.

VirtualMachineConfig improves vzVirtualMachineConfiguration because it
also keeps around the config.VirtualMachine go object which was used to
created the vz.VirtualMachineConfiguration object. This will be useful
in simplifying the code using the pkg/vf package.

Similarly to the vf.VirtualMachineConfiguration type introduced in the previous
commit, the vf.VirtualMachine type wraps both a vz.VirtualMachine
instance, and the vfkit/go data which was used to generate it, which is
the aforementioned VirtualMachineConfiguration type.

This allows to simplify some users of pkg/vf, in particular the rest
code. `code-hex/vz` is now only imported in pkg/vf
