CacheMetrics is a general counter that is used for all possible caches.
For caches that we do not support, there is no need to go and fetch
their values.
When moving to the APITimer each such request will take longer (the
value will not be available as it use it) now it will be possible to
supply a null as a url which would cause to the metrics to return 0 for
all counters.

This patch changed how broadcast address is deduct. It Adds a reverse

Fix the stubbed implementation of forceRepairRangeAsync() which is
used, for example, when the "--start-token"/"--end-token" options are
passed to "nodetool repair".
forceRepairRangeAsync() works similarly to the existing forceRepairAsync()
just sending the additional start/end tokens as two new options to the
REST API. Unlike the parallel Cassandra code, we don't do any fancy
processing on these tokens to intersect them with the node's token ranges -
we'll do this intersection in the C++ code, where the repair is actually
done.
