All features are now covered by rskafka. This also removes the need to
specify a server ID for write buffer consumers. This was only used for
rdkafka since there we needed to specify a consumer group, even though
we did not use any transactions.
The direction was required when a database could read or write from/to a
write buffer. Now it is clear from the usage context of a write buffer
context which of the two applications is meant (databases read, routers
write) so the direction flag is no longer required.
