Make replica selection deterministic in read_repair_test
----
> Some tests in read_repair_test are flakey
> -----------------------------------------
>
> Key: CASSANDRA-14244
> URL: https://issues.apache.org/jira/browse/CASSANDRA-14244
> Project: Cassandra
> Issue Type: Test
> Components: Testing
> Reporter: Sam Tunnicliffe
> Assignee: Sam Tunnicliffe
> Priority: Major
> Labels: dtest
>
> Since being refactored for CASSANDRA-14134,
> {{test_alter_rf_and_run_read_repair}} and {{test_read_repair_chance}} in
> {{read_repair_test.TestReadRepair}} are flakey and regularly fail on all
> branches. The problem is that the inital setup of these two tests doesn't
> explicitly set the {{read_repair_chance}} or {{dclocal_read_repair_chance}}
> properties on the test table. As a consequence, read repairs are sometimes
> probabilistically triggered and query results don't match the expectations.
