Added a new table engine backed by Apache Kafka,
it allows near real-time ingestion or ETL with
exactly-once semantics.
It doesn’t store any data on disk, so data must
be materialized into a physical table to allow
random access.
Currently it only supports reading, no insertion.
This allows sending notifications to supported
table engines when their dependencies change.
For example, a table can be notified when a
MATERIALIZED VIEW is attached to it.
This is a building block for building pipelines.
* the alpha_map vector always (de)serialises
the actual version (could empty sometimes)
* AggregateFunctionTopK generic variant deserialises
it as well instead of ignoring it
* AggregateFunctionTopK generic variant clears the
array before deserialising
