Subject: [PATCH] Save the pre-timeout interrupt in dbus property

Get the watchdog pre-timeout interrupt value from ipmi watchdog set command,
and store it into dbus property.

Tested:
Config IPMI watchdog: BIOS FRB2 Power Cycle after 1 seconds:
ipmitool raw 0x06 0x24 0x01 0x13 0x0 0x2 0xa 0x00
Start watchdog:
Ipmitool mc watchdog reset
Check the watchdog pre-timeout interrupt in below:
