Add configuration to decide the amount of slots that will be used in a VM - This will limit the amount of times that memory can be hotplugged. - Use memory slots provided by user. - tests: aling struct cli: kata-env: Add memory slots info. - Show the slots to be added to the VM. ```diff [Hypervisor] MachineType = "pc" Version = "QEMU ..." Path = "/opt/kata/bin/qemu-system-x86_64" BlockDeviceDriver = "virtio-scsi" Msize9p = 8192 + MemorySlots = 10 Debug = false UseVSock = false ``` Fixes: #751 Signed-off-by: Jose Carlos Venegas Munoz <jose.carlos.venegas.munoz@intel.com>
