Add EX option for SET command, to set TTL for the key.
A behavior of SET EX is same as SETEX command, it just different syntax.
see: https://redis.io/commands/set
"Enabling TTL feature, add setex and ttl commands to use it."
* 'redis_setex_ttl' of git://github.com/syuu1228/scylla:
redis: add test for setex/ttl
redis: add ttl command
redis: add setex command
The error message (silently) changed to "DB index is out of range" the
following commit:
c7a4e694ad
The new error message is part of Redis 4.0, released in 2017, so let's
switch Scylla to use the new one.

Merged pull request https://github.com/scylladb/scylla/pull/5381 by
Peng Jian, fixing multiple small issues with Redis:
* Rename the options related to Redis API, and describe them clearly.
* Rename redis_transport_port to redis_port
* Rename redis_transport_port_ssl to redis_ssl_port
* Rename redis_default_database_count to redis_database_count
* Remove unnecessary option enable_redis_protocol
* Modify the default value of opition redis_read_consistency_level and redis_write_consistency_level to LOCAL_QUORUM
* Fix the DEL command: support to delete mutilple keys in one command.
* Fix the GET command: return the empty string when the required key is not exists.
* Fix the redis-test/test_del_non_existent_key: mark xfail.
Support to delete multiple keys in one DEL command.
The feature of returning number of the really deleted keys is still not supported.
Return empty string to client for GET command when the required key is not exists.
Fixes: #5334
