cephadm/samples: don't specify localhost as grafana addr

Grafana complains about this being set to localhost
and also appears to be able to figure out what to bind to
itself if this field is not set. In actual deployments
this would be set by the cephadm mgr module while the
test_cephadm workunit itself just directly passes
a json config
