Renames a key and overwrites the destination.
RENAME key newkey
Renames key to newkey. It returns an error
when key does not exist.
If newkey already exists, it is overwritten. By default,
Valkey uses implicit lazy freeing (similar to UNLINK), so
large values are released asynchronously. If lazy freeing is disabled
and synchronous deletion is configured, overwriting a key with a very
large value may cause high latency.
In Cluster mode, both key and newkey must
be in the same hash slot, meaning that in practice only
keys that have the same hash tag can be reliably renamed in cluster.
