Add suppress_type_name to stop warnings with ES7

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.
