VmConfig and its nested configuration structs, the VmInfoResponse
wrapper and DeviceNode serialize their Option<T> fields as JSON null
when unset. The OpenAPI specification types these fields as
non-nullable, so strict client generators (for example ogen for Go)
reject /vm.info responses and cannot generate a working API client.
Apply serde_with's skip_serializing_none to the affected structs so
that unset optional fields are omitted from the serialized JSON instead
of being emitted as null. API responses now validate against the
existing specification unchanged; no nullable annotations are required.

This better aligns with the rest of the code and makes it clearer
that these tests can run "as is" in a normal hosted environments
without the special test environment.

Historically the Cloud Hypervisor coding style has been to ensure that
all imports are ordered and placed in a single group. Unfortunately
cargo fmt has no support for ensuring that all imports are in a single
group so if whitespace lines were added as part of the import statements
then they would only be odered correctly in the group.
By adopting "group_imports="StdExternalCrate" we can enforce a style
where imports are placed in at most three groups for std, external
crates and the crate itself. Choosing a style enforceable by the tooling
reduces the reviewer burden.

The current implementation of breadth first traversal for device tree
uses a temporary vector, therefore causes unnecessary memory copy.
Remove it and do it within vector nodes.

By having the DeviceNode storing a PciBdf, we simplify the internal code
as well as allow for custom Serialize/Deserialize implementation for the
PciBdf structure. These custom implementations let us display the PCI
s/b/d/f in a human readable format.

This crate was used in the integration tests to allow the tests to
continue and clean up after a failure. This isn't necessary in the unit
tests and adds a large build dependency chain including an unmaintained
crate.

Extend and use the existing DeviceTree to retrieve useful information

Its test case calls remove unconditionally. Instead of making the test
code call remove conditionally, removing the pci_support dependency
simplifies things -- that function is just a wrapper around HashMap's
remove function anyway.

We need a way to store the information about where a PCI device was
placed on the PCI bus before the VM was snapshotted. The way to do this
is by adding an extra field to the DeviceNode structure.
