docs: This removes some critical state from the Redis shards.
  
      In a multitenant environment, this will flush metadata for all jobs, which
      may be undesirable.
  
      This removes all of the metadata for objects that have been evicted. This
      can be used to try to address out-of-memory errors caused by the
      accumulation of metadata in Redis. However, after running this command,
      fault tolerance will most likely not work.
