Overwriting with SET removes the expire time
After a pexpire time is set, if SET is run on the same key, the expire time is removed and the key is not deleted.
Commands like this are set, getset.
Commands such as incr, lpush, sadd, zadd, and hset do not remove the expire time.

| Command> | set key value |
| Result> | 1 |
| Command> | pexpire key 5000 string |
| Result> | 1 |
| Command> | pttl key string |
| Result> | 3546 |
| Command> | set key new_value |
| Result> | 1 |
| Command> | pttl key string |
| Result> | -1 |
| Command> | get key |
| Result> | new_value |
RENAME does not remove the expire time
Changing the key name does not remove the expire time.
