Memory hotplug test

Summary: Implement memory hotplug testing for 'make check'.

• Refactor "-m mem,slots,maxmem" to MachineClass properties and replace related global variables where they are still used with properties. Make "set_memory_options()" use new properties leaving only CLI parsing there. Goal is to make "set_memory_options()" function a thin wrapper that takes care of CLI parsing and makes CLI option '-m' an alias to new -machine mem/mem-slots/maxmem options.
• Create a set of basic tests for 'make check' to verify that -m/-machine CLI parsing works as expected and based on that a set memory hot-add tests using QMP introspection to verify the expected behaviour.
