The standalone `--balloon` parameter being fully functional at this
point, we can get rid of the balloon options from the --memory
parameter.

This changeset extends the documentation with the UEFI and Windows
related info. The focus is on providing consumer with a minimum
necessary and proper piece of the information to enter the features
quickly. While UEFI is a cross platform topic, it is a required
prerequisite for the Windows usage.

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.

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.

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.
