Limit number of parallel config apply connections to 100 (#12663)

Browse Source 
## Problem

See https://databricks.slack.com/archives/C092W8NBXC0/p1752924508578339

In case of larger number of databases and large `max_connections` we can
open too many connection for parallel apply config which may cause `Too
many open files` error.

## Summary of changes

Limit maximal number of parallel config apply connections by 100.
