[Service] Debugging condole.log with ServiceMessage

[Service] Debugging condole.log with ServiceMessage

There is no way to get the console message with commercial products
because Tizen SDK cannot get the 'dlog' actually.
 - 'dlog' is disabled on release firmware.

Thus, this way provides a new way to catch the console message of
service application by UI application's message port
 - local message port 'wrt.message.port'
 - message format : {'service-log' : message }
