Currently, in case a blocked command is unblocked externally (eg. due to the relevant slot being migrated or the CLIENT UNBLOCK command was issued, the command statistics will always update the failed_calls error statistic. This leads to missalignment with valkey-io@90b9f08 as well as some inconsistencies. For example when a key is migrated during cluster slot migration, clients blocked on XREADGROUP will be unblocked and update the rejected_calls stat, while clients blocked on BLPOP will get unblocked updating the failed_calls stat. In this PR we add explicit indication in updateStatsOnUnblock thet indicates if the command was rejected or failed. Signed-off-by: ranshid <ranshid@amazon.com>
