[enhencement](config) change default memtable size & loadStreamPerNode & default load parallelism (#28977)

Browse Source 
We change memtable size from 200MB to 100MB to achieve smoother flush
performance. We change loadStreamPerNode from 20 to 60 to avoid stream
rpc to be the bottleneck when enable memtable_on_sink_node. We change
default s3&broker load parallelsim to make the most of CPUs on moderm
multi-core systems.
