This commit is the beginning of an effort to split bridges into a
connector part and a bridge part.
Several bridges should be able to share a connector pool defined by a
single connector. The connectors should be possible to enable and
disable similar to how one can disable and enable bridges. There should
also be an API for checking the status of a connector and for
add/edit/delete connectors similar to the current bridge API.

This commit makes it possible to configure if a Kafka bridge should work
in query mode sync or async by setting the resource_opts.query_mode
configuration option.
