Add "ClickHouse engine" limitation (#936)

Currently Quesma auto-creates tables with `MergeTree` engine. It's
automatically converted to `ReplicatedMergeTree` in case of ClickHouse
Cloud, but not in case of a local multi-node cluster and the user can't
control it.

If the user has a local multi-node cluster, the tables automatically
created by Quesma won't be replicated - the only solution is to create
them manually with the correct `ReplicatedMergeTree` engine.

+### ClickHouse limitations
+* When using a cluster deployment of ClickHouse, the tables automatically created by Quesma (during [Ingest](/ingest.md)) will use the `MergeTree` engine. If you wish to use the `ReplicatedMergeTree` engine instead, you will have to create the tables manually with  `ReplicatedMergeTree` engine before ingesting data to Quesma.
+  * *Note: On ClickHouse Cloud, the tables automatically created by Quesma will use the `ReplicatedMergeTree` engine (ClickHouse Cloud default engine).*
