sysmobts: Begin to add various limits and actions

The idea is that for different parts of the system we can define
thresholds for warning and critical (severe) temperate thresholds.
And once any of these temperatures is reached we will execute an
action. When crossing from NORMAL to WARNING or WARNING to SEVERE
we will need to apply some hysteris before switching back to the
lower level. E.g. when being SEVERE mode, at least wait until we
are below the warning level again. Besides being able to switch
off things we could start reducing the transmit power of the system
until the system is cold enough again.

No action is implemented so far, everything is varpoware!
