Cache system GUID in netipmid
GUID is used in the IPMI session setup steps RAKP12 and RAKP34.
The GUID is read from the DBUS property. It is observed that
when the host is booting, reading the GUID takes a significant
delay and the session setup fails with ipmitool. Since GUID doesn't
change for a machine, it is safe to cache GUID in the netipmid and
speed up the session setup.
