[PATCH v5 2/3] job: introduce dump guest memory job

There's no way to cancel the current executing dump process, lead to the virtual machine manager daemon((e.g. libvirtd) cannot restore the dump job after daemon restart. Introduce dump guest memory job type, and add an optional 'job-id' argument for dump-guest-memory QMP to make use of jobs framew
