To be done after #1405 gets merged

Currently Lettuce 5.1 is the only instrumentation that logs the full db.statement, all others are just logging the command. DB semantic convention says that we should log full statement if possible:

For Redis, the value provided for db.statement SHOULD correspond to the syntax of the Redis CLI. If, for example, the HMSET command is invoked, "HMSET myhash field1 'Hello' field2 'World'" would be a suitable value for db.statement.

The aim of this issue is to straighten this out and use RedisCommandNormalizer in all Redis instrumentations (where it's possible to do so).
