4e1b78e1ff vmm: Add 'hotplugged_size' to memory parameters
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.

c645a72c17 vmm: Add 'hotplug_size' to memory zones
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.

e15dba2925 vmm: Rename NUMA option 'id' into 'guest_numa_id'
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.
