      As part of SERVER-130568 we wanted to enable the random_ddl_crud_setFCV_operations jstest to run with concurrent add/remove shard operations.

      However, it turns out that the add_remove_shards hook does not support concurrent setFCV operations due to two reasons:

      1. It doesn't handle resharding failures due to FCV interruptions
      2. If the setFCV operation happens right after choosing whether to use the old or new path for shard removal then it encounters a CommandNotSupported failure
