Is your feature request related to a problem? Please describe.
Currently, when you create a changefeed job for a table, the job will publish to a topic named after the table. If a database has N tables, you will need to create N Kafka topics, which can be an annoyance.

Describe the solution you'd like
Ideally, you would be able to tell multiple change feed jobs to emit to the same topic, so you can have one topic per database (and every change feed will emit to that database topic).

Describe alternatives you've considered
There don't appear to be any alternatives to the current flow.
