The objectives of this ticket are:
- Considering that all the concurrency suites run on both feature flags enabled and normal variants, the test must not run on the normal variants until SERVER-52465 is finished.
- The does_not_support_stepdowns tag must be deleted from the test once all resiliency is implemented on the commands, so all concurrency tests with stepdowns should run perfectly.
- The test should run on the concurrency_sharded_replication suite.
- The concurrency_sharded_ddl_operations suite should be removed
