Currently unimplemented. Once implemented, this API will allow for
creating virtio-fs devices in the VM after it has booted.

This ensures that the field is filled with None when it is not specified
as part of the deserialisation step.

This allows the validation of this requirement for both command line
booted VMs and those booted via the API.

Replace the existing VmConfig::valid() check with a call into
.validate() as part of earlier config setup or boot API checks.

The configuration comes from a variety of places (commandline, REST API
and restore) however some validation was only happening on the command
line parsing path. Therefore introduce a new ability to validate the
configuration before proceeding so that this can be used for commandline
and API boots.
For now move just the console and serial output mode validation under
the new validation API.

Now that the restore path uses RestoreConfig structure, we add a new
parameter called "prefault" to it. This will give the user the ability
to populate the pages corresponding to the mapped regions backed by the
snapshotted memory files.

The goal here is to move the restore parameters into a dedicated
structure that can be reused from the entire codebase, making the
addition or removal of a parameter easier.

The parse_size helper function can now be consolidated into the
ByteSized FromStr implementation.

Now all parsing code makes use of the Toggle and it's FromStr support

The integration tests and documentation make use of empty value strings

This simplifies the parsing of the option by using OptionParser along
with its automatic conversion behaviour.

Byte sizes are quantities ending in "K", "M", "G" and by implementing
this type with a FromStr implementation the values can be converted
using .parse().

Before porting over to OptionParser add a unit test to validate the
current memory parsing code. This showed up a bug where the "size=" was
always required. Temporarily resolve this by assigning the string a
default value which will later be replaced when the code is refactored.

This commit adds new option hotplug_method to memory config.
It can set the hotplug method to "acpi" or "virtio-mem".

This opens the backing file read-only, makes the pages in the mmap()
read-only and also makes the KVM mapping read-only. The file is also
mapped with MAP_PRIVATE to make the changes local to this process only.
This is functional alternative to having support for making a
virtio-pmem device readonly. Unfortunately there is no concept of
readonly virtio-pmem (or any type of NVDIMM/PMEM) in the Linux kernel so
to be able to have a block device that is appears readonly in the guest
requires significant specification and kernel changes.

When using "--disk" with a vhost socket and not using self spawning then
it is not necessary or helpful to specify the path.
