Now that we're adding support to rename a sharded collection, we want to ensure it works properly in the presence of stepdowns, and historically, fuzzers have been helpful detecting bugs. There are two main things to ensure after the completion of this ticket:

• The jstestfuzz_sharded_continuous_stepdown suite is using the rename of sharded collections
• The jstestfuzz_sharded_continuous_stepdown suite is trying the new paths of DDL operations
