Add a couple of logging info to track time between activities, first
is from after the Popen(launch_cmd) to after qmp.connect(), second is
from qmp.connect() to the release of the qemu via the qmp("cont") command
this includes the mmap() activity.
Example output:
QMP connected to QEMU at 06/24/21 11:11:56 and took 0.9556229114532471 seconds
from launch
QMP released QEMU at 06/24/21 11:11:56 and took 0.26789021492004395 seconds
from connect
