Gleb Natapov 807e37502a db/consistency_level: do not use result from heat weighted load balancer if it contains duplicates 
Because of https://github.com/scylladb/scylladb/issues/9285 heat weighted
load balancer may sometimes return same node twice. It may cause wrong
data to be read or unexpected errors to be returned to a client. Since
the original bug is not easy to fix and it is rare lets introduce a
workaround. We will check for duplicates and will use non HWLB one if
one is found.

Fixes scylladb/scylladb#20430

Closes scylladb/scylladb#20414
