Andrei Chekun bbb6c3c2ff test.py: Add resource consumption metrics ...

This PR adds the possibility to gather resource consumption metrics. The collected metrics can be used to compare performance before and after specific changes aimed at increasing performance. Currently, this functionality works only in manual mode, and this is just raw data. Later on, these metrics can be used in Jupyter notebook to analyze and visualize how the resources are used and can provide the insight on how to improve it. This PR is a first insight after gathering these metrics.

Add the possibility to gather resource consumption for the test.py execution. SQLite DB will be created with different performance metrics that will allow comparing the resource consumption between changes.
The DB will be in the tmp directory that by default set to testlog. Across the runs, the DB will not be deleted, so each new run will just add information to the existing DB.
Parameter --get-metrics was added to switch on or off the metrics gathering. By default, it's switched on.
