cthulhu: handle servers with multiple CRUSH names
cthulhu: handle servers with multiple CRUSH names

For example, when I have two CRUSH nodes for host
'foo', they may be called 'foo' and 'foo-ssd'.  This
patch handles that case by realising that both actually
refer to the same server.

Fixes: #8463
