When starting 'memory_peak' service is using python command instead of
python3, while psutil (required package) is most probably being
installed into the python3 environment (as we are dropping python2.7
support).

Without this patch, the pmap -XX call fails on openSUSE Leap
distributions as those have a fairly ancient procps version that
does not support the -XX parameter. A pure python implementation
is more portable, faster and even shorter than the subprocess
call.

psutil is only installed under python3 for the 3.5 gate jobs. Call
mlock_report.py with $PYTHON so we support both environments.
Updates to mlock_report.py for python3 compatability

The change makes peakmem_tracker list processes that lock memory pages
from swapping to disk. It may be helpful when debugging oom-killer job
failures in gate in case when dstat shows that swap is not fully used
when oom-killer is triggered.
The peakmem_tracker service was renamed into memory_tracker to reflect
its new broader scope.
