Added functions for changing the max_power_red in case of we receive
a Failure Event report from the manager. The sbts2050 change the
max_power_red to the value that we have configured in the manager
and the sbts2050 restore this value to the initial value if the bts
don't receive another Failure Event report in the same time that we
check the temperature in the manager.
