ADBC - OS-level driver manager

[David Coe]

ODBC has different OS-level driver managers available on their respective 
systems. It seems like the current driver 
manager<https://arrow.apache.org/adbc/main/cpp/driver_manager.html> work has 
been largely targeting an app-specific implementation. Have there been any 
discussions of ADBC having a similar system-wide driver registration paradigm 
like ODBC does?
