[PATCH phosphor-host-ipmid] Add ipmi cold-reset command, which call a dbus method. 1. A method dbus_cold_reset() to talk with the dbus method 'place_holder'; 2. Also get service name by object mapper which is object_mapper_get_connection(); 3. Register the ipmi command; 4. Add related .o to the Makefile.
