Review Comment:
+1 not to break backward compatibility here.
But it is better to go with default value as -1 and the validation can be -1
or >0.
We can clarify the doc adding with the below text for better clarity.
"The default value of -1 means that this will be set to the configured value
of `remote.log.manager.thread.pool.size`, if available; otherwise, it defaults
to 10" .
