The connection reuse and stale connection logs printed the raw heap address of the connection object, which ends up in the host application logs (e.g. `system.text_log` in ClickHouse) and discloses the memory layout. Co-Authored-By: Claude Opus 5.5 <[email protected]>

Motivation
The "Got connection from pool" and "Deleting stale connection from pool" logs of
ConnectionPool::getConnectionAsyncprintcnx.get(), the heap address of the connection object. It adds nothing to the pool key that is already logged, and it puts the memory layout of the process into the application logs.Modifications
Remove the pointer from both log lines.
