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

QEMU Emulation Targets ====================== To simplify development, the build system supports building images to work with the QEMU emulator in system emulation mode. Several architectures are currently supported in 32 and 64 bit variants: * ARM (qemuarm + qemuarm64) * x86 (qemux86 + qemux86-64) * PowerPC (qemuppc only) * MIPS (qemumips + qemumips64) Use of the QEMU images is covered in the Yocto Project Reference Manual. The appropriate MACHINE variable value corresponding to the target is given in brackets.
