      Description

      test_simple_bootstrap_mixed_versions is failing due to CASSANDRA-13004, which introduced "cassandra.force_3_0_protocol_version" for schema migrations during upgrades from 3.0.14 upwards. This flag is missing in `test_simple_bootstrap_mixed_versions` while we are adding/bootstrapping 3.11.4 node to an existing 3.5 version of C* node, which resulted in ks keyspace schema/data not being bootstrapped to the new node.

      I debugged and confirmed that MigrationManager::is30Compatible is returning false which is forcing MigrationManager::shouldPullSchemaFrom to return false as well.

      from debug logs:

      DEBUG [GossipStage:1] 2019-02-06 23:20:47,392 MigrationManager.java:115 - Not pulling schema because versions match or shouldPullSchemaFrom returned fal
