SNOW-1821246 Add parameter for blob upload timeout

[sfc-gh-alhuang]

The original blob upload timeout is hard coded as 5 seconds. This might not be feasible for Iceberg table streaming as the 30 seconds client lag in Iceberg streaming might create larger file which requires larger blob upload timeout. Make the BLOB_UPLOAD_TIMEOUT constant to configurable parameter and keep the default timeout of FDN table streaming as 5 seconds while have a 20 seconds default for Iceberg table streaming.

Want to make sure we understand the upload logic correctly, the total wait time is NOT 5 seconds, the total time is BLOB_UPLOAD_TIMEOUT_IN_SEC * BLOB_UPLOAD_MAX_RETRY_COUNT which is 120s, and currently the BLOB_UPLOAD_MAX_RETRY_COUNT is already configurable. Ideally we do not want to exposing more and more configurable parameters even though they're not documented. And please make sure you have read the comment in the upload function

        // In order to guarantee fairness between the time spent on waiting blob uploading VS blob
        // registering and make sure the delay on server side commit is relatively small:
        // 1. If no exception and total time is less than or equal to
        // BLOB_UPLOAD_TIMEOUT_IN_SEC * 2, we will wait for all blobs to be uploaded and then
        // register them
        // 2. If no exception and total time is bigger than BLOB_UPLOAD_TIMEOUT_IN_SEC * 2, we
        // will break the waiting and register the processed blob first
        // 3. If hitting non-timeout exception, we will skip the current blob and continue on
        // processing next blob
        // 4. If hitting timeout exception, we will break the waiting if we haven't reached
        // BLOB_UPLOAD_TIMEOUT_IN_SEC * BLOB_UPLOAD_MAX_RETRY_COUNT and register the
        // processed blob first. Otherwise, we will skip the current blob and continue on processing
        // next blob if time out has been reached.
