"
The topology object maintains all sort of node/DC/RACK mappings on
board. When new entries are added to it the DC and RACK are taken
from the global snitch instance which, in turn, checks gossiper,
system keyspace and its local caches.
This set make topology population API require DC and RACK via the
call argument. In most of the cases the populating code is the
storage service that knows exactly where to get those from.
After this set it will be possible to remove the dependency knot
consiting of snitch, gossiper, system keyspace and messaging.
