            Log:
            introduce a variable which skips systemd-sleep services

The automated TC contains a phase where services systemd-hybrid-sleep
and systemd-hibernate are started for testing purposes. Unfortunately,
running these services had real consequences on machines in certain
environments where the TC was executed (for example: machines became
unresponsive).
To have some control of the situation, a new environment variable was
introduced. It is called REAL_SCENARIOS and it can avoid the situation
when set to false. Default value of the variable is true which means
that above-mentioned services will be executed.
