We implement the builtin function
redis.log()
for the Lua script,but the log level was different between Redis and Kvrocks, so we
choose to keep consistency with Redis's log level to avoid compatible
problem with the below mappings(which would make the legacy script happy):
LOG_DEBUG => NULL
LOG_VERBOSE => INFO
LOG_NOTICE => INFO
LOG_WARNING => WARNING
LOG_DEBUG would never work since the debug level make no sense in kvrocks
