benchmark getRedisConfig exit only when meet NOAUTH error (redis#11096)

redis-benchmark: when trying to get the CONFIG before benchmark,
avoid printing any warning on most errors (e.g. NOPERM error).
avoid aborting the benchmark on NOPERM.
keep the warning only when we abort the benchmark on a NOAUTH error
