Most stress test has probable behaviour, the longer test run the
larger corner cases will be cover. It is reasonable to allow
user to provide some sort of system load factor.
This patch introduce two global variables
LOAD_FACTOR: Usually means factor number of running tasks
TIME_FACTOR: Usually means factor of run time, or number of operations
If not speficied both variables defined to 1, so original behaviour
preserved.

TODO: Change all stress tests to use this variables
