Stability test execution

Stability tests are created for memory leak checking. Currently this is semi-manual.

Please start the robot test case first with:

# tox -e stability

Then, in other terminal, check what is the pid of the python process:

# pidof python

Alternatively, you can use:

# pstree -al | less

Please note that there are at least two python processes: one for running the robot test case and the other running the hello command in a loop in python So, you likely want to check the pid of latter one:

# watch cat /proc/<pid>/status

If you like to check memory leaks, please verify that VmSize does not increase (It may well go up a bit before the garbage collector is activated so please verify that the maximum does not increase over the time).
