Add the new option 'hotplugged_size' to both --memory-zone and --memory
parameters so that we can let the user specify a certain amount of
memory being plugged at boot.
This is also part of making sure we can store the virtio-mem size over a
reboot of the VM.

Implement a new VM action called 'resize-zone' allowing the user to
resize one specific memory zone at a time. This relies on all the
preliminary work from the previous commits to resize each virtio-mem
device independently from each others.

In anticipation for resizing support of an individual memory zone,
this commit introduces a new option 'hotplug_size' to '--memory-zone'
parameter. This defines the amount of memory that can be added through
each specific memory zone.
Because memory zone resize is tied to virtio-mem, make sure the user
selects 'virtio-mem' hotplug method, otherwise return an error.

The goal of this commit is to rename the existing NUMA option 'id' with
'guest_numa_id'. This is done without any modification to the way this
option behaves.
The reason for the rename is caused by the observation that all other
parameters with an option called 'id' expect a string to be provided.
Because in this particular case we expect a u32 representing a proximity
domain from the ACPI specification, it's better to name it with a more
explicit name.

Use of backing file is deprecated hence use the `hugepages` field.
Also use the `boot` field for specifying number of cpus

Use updated --memory option parameters. The field `size` needs
M/G suffix. Without the suffix cloud-hypervisor panics at
src/main.rs:353
Also the use of backing file is deprecated so use `shared` field

With recent changes (#1030#1084), the '/vm.remove-device' API is no
longer restricted to remove VFIO PCI devices. It now supports (almost)

Now that our CI has transitioned from ClearLinux to Ubuntu images

Now that the project relies on Ubuntu images, the documentation related

Currently, not every feature of the cloud-hypervisor is enabled
on AArch64, which means that on AArch64 machines, the
`run_unit_tests.sh` needs to be tailored and some unit test cases
should be run on x86_64 only.
Also this commit fixes the typo and unifies `Arm64` and `AArch64`
in the AArch64 document.
Signed-off-by: Henry Wang <Henry.Wang@arm.com>
The support of AArch64 is in very early stage. The steps in building and
runing on X86 and AArch64 can not align well yet. Adding AArch64 content
to README.md would produce much divergence.
Adding a guide in docs/ folder could be a better way to start now.

The action of "vm.delete" should not report errors on non-booted
VMs. This patch also revised the "docs/api.md" to reflect the right
'Prerequisites' of different API actions, e.g. on "vm.delete" and
"vm.boot".

A new ClearLinux image has been uploaded to the Azure storage account.
It is based off of the ClearLinux cloudguest image 31310 version, with
three extra bundles added to it.
First bundle is curl, which adds the curl binary to the image, second
bundle is iperf, adding the iperf binary to the image, and third bundle
is sysadmin-basic to include utility like netcat.
The image is 2G in size.

The cache= option from the virtiofsd backend is meant to be used
depending on how the user wants to use the guest page cache. For most
use cases, we want to bypass the guest page cache to reduce the guest
memory footprint, which is why "cache=none" should be the default.
"cache=always" is the other option when the user wants to do something
specific by using the guest page cache, but should not be the default
anymore.
