memtest: Test the actual available memory of VPS under Linux

The amount of memory is an important indicator for VPS, but because some hosting providers oversell their VPS, the actual amount of available memory allocated may not reach the nominal amount of memory. The memtest tool can test the maximum value of the actual available memory of the VPS. The VPS evaluation tool memtest continuously increases the amount of memory filled until the memory is occupied and the process is killed.
