Before this patch, trying to create a materialized view when tablets are enabled for a keyspace results in a failure: "Tablet map not found for table <uuid>", with uuid referring to the new view. When a table schema is created, the handler on_before_create_column_family() is called - and this function creates the tablet map for the new table. The bug was that we forgot to do the same when creating a materialized view - which also a bona-fide table. In this patch we call on_before_create_column_family() also when creating the materialized view. I decided *not* to create a new callback (e.g., on_before_create_view()) and rather call the existing on_before_create_column_family() callback - after all, a view is a column family too. This patch also includes a test for this issue, which fails to create the view before this patch, and passes with the patch. The test is in the test/topology_experimental_raft suite, which runs Scylla with the tablets experimental feature, and will also allow me to create tests that need multiple nodes. However, the first test added here only needs a single node to reproduce the bug and validate its fix. Fixes #16194. Signed-off-by: Nadav Har'El <nyh@scylladb.com> Closes scylladb/scylladb#16205
