New Command: Rename Hash Fields

Announcing a new command KEYDB.HRENAME. The syntax is:
keydb.hrename [hash] [old_fieldname] [new_fieldname]

The command simply renames the hash field to the new value keeping the stored value. If an existing field is named the same as the destination that field will be overwritten.

It’s designed to save workaround as described here: https://rdbtools.com/blog/redis-rename-fields-in-hash-multiple-keys-in-redis/

The command is in the unstable branch and will be available in our 6.0 release.
