Adding additional arguments to databases

[M1ha-Shvn]

Hi
How to add additional arguments to database_configs?
To be concrete, I use pgbouncer and want to add DISABLE_SERVER_SIDE_CURSORS parameter. How can I achieve it without hacky:

for db in DATABASES.values():
    db['DISABLE_SERVER_SIDE_CURSORS'] = True

We can update the function to allow you to pass additional options?
