thermal: Add new Thermal Monitor module

PASS can monitor the various h/w resource such as CPU/GPU and so on.
The thermal information is one of them. Require the thermal monitoring
and then notify the meaningful data of thermal. So, Thermal Monitor
is required.

Thermal Monitor supports the configuration file in order to define
the thermal scenarios (e.g., ReleaseAction, ShutdownAction) according to
the user definition. It is very flexible to define the multiple thermal
scenarios. Thermal Monitor monitors the thermal information using
following two methods:
- uevent-based thermal monitoring (interrupt method)
- timer-baesd thermal monitoring (polling method)

[d-bus interface]
- d-bus interface: "org.tizen.system.pass.monitor.thermal"
- d-bus method : "thermal_scenario"
- configuration : /etc/pass/pass-thermal.conf
