Add more log when delete orphan node

we have following log when delete opphan node
INFO nova.compute.manager Deleting orphan compute node xx

we might need to know why those node are removed so
we need additional log info about the removal.
however, it's not complete about why it's removed and
what's removed unless we dig into database layer
