dclocal_read_repair_chance and read_repair_chance have been removed in Cassandra 3.11 and 4.x, see https://issues.apache.org/jira/browse/CASSANDRA-13910. if we expose the properties via DDL, Cassandra would fails to consume the CQL statement to creating the table when performing migration from Scylla to Cassandra 4.x, as the latter does not understand these properties anymore. currently the default values of `dc_local_read_repair_chance` and `read_repair_chance` are both "0". so this is practically disabled, unless user deliberately set them to a value greater than 0. also, as a side effect, Cassandra 4.x has better support of Python3. the cqlsh shipped along with Cassandra 3.11.16 only supports python2.7, see https://github.com/apache/cassandra/blob/cassandra-3.11.16/bin/cqlsh.py it errors out if the system only provides python3 with the error of ``` No appropriate python interpreter found. ``` but modern linux systems do not provide python2 anymore. so, in this change, we deprecate these two options.

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.
