When using elasticsearch 7 with fluentd, you seem to get a lot
of warnings in the docker logs output that look like:
[types removal] Specifying types in bulk requests is deprecated.
The docs suggest adding suppress_type_name to stop these warnings,
and that seems to work without affecting any functionality.
