When replication strategy class is created caller parr const reference on the config options which is, in turn, a map<string, string>. In the future r.s. classes will need to get "scylla specific" info along with legacy options and this patch prepares for that by passing more generic params argument into constructor. Currently the only inhabitant of the new params is the legacy options. Signed-off-by: Pavel Emelyanov <xemul@scylladb.com>
