This new option allows the user to define a list of SGX EPC sections
attached to a specific NUMA node.

Make sure the unique PCI bus is tied to the default NUMA node 0, and
update the documentation to let the users know about this special case.

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

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.

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.
