[performance](load) increase max_broker_concurrency to 100

[kaijchen]

What problem does this PR solve?

Increase default max_broker_concurrency to 100 to improve broker load performance.
This option will affect the max number of scan / sink instances allowed in a broker load.

parallel instance = min(max_broker_concurrency,
                        source file size / min_bytes_per_broker_scanner,
                        num backends * load_parallelism)

S3 load time of tpcds_1000g catalog_sales:

• before: 438s
• after: 225s
