We were recently surprised (in pull request #25797) to "discover" that Scylla does not allow granting SELECT permissions on individual materialized views. Instead, all materialized views of a base table are readable if the base table is readable. In this patch we document this fact, and also add a test to verify that it is indeed true. As usual for cqlpy tests, this test can also be run on Cassandra - and it passes showing that Cassandra also implemented it the same way (which isn't surprising, given that we probably copied our initial implementation from them). The test demonstrates that neither Scylla nor Cassandra prints an error when attempting to GRANT permissions on a specific materialized view - but this GRANT is simply ignored. This is not ideal, but it is the existing behavior in both and it's not important now to change it. Additionally, because pull request #25797 made CDC-log permissions behave the same as materialized views - i.e., you need to make the base table readable to allow reading from the CDC log, this patch also documents this fact and adds a test for it also. Fixes #25800 Closes scylladb/scylladb#25827

If you can use an existing folder, consider adding your test to it. New folders should be used for new large categories/subsystems, or when the test environment is significantly different from some existing suite, e.g. you plan to start scylladb with different configuration, and you intend to add many tests and would like them to reuse an existing Scylla cluster (clusters can be reused for tests within the same folder).
To add a new folder, create a new directory, and then
copy & edit its suite.ini.
