Add support for Redis 6 ACLs in the `Redis`, `RedisCluster`, and `RedisArray` classes.
On a related note, it adds a mechanism for users to customize how we generate persistent connection IDs such that they can be grouped in different ways depending on the specific use case required (e.g. it would allow connections to be grouped by username, or by user-defined persistent_id, or both).
Right now cloning the repo and running unit tests will all fail if the
Redis/RedisCluster instances aren't configured with the password
'phpredis'.
This commit simply makes authentication during the tests optional via a
command-line argument.
This commit implements UNLINK for Redis, RedisCluster, and RedisArray.
To a client library UNLINK behaves identically to DEL so we can use the
same handlers for both.
* Added a test specifically for RedisCluster to test slave failover
settings.
* Added an option to specifically disable colorization, as well as
a mechanism to determine if the output is being piped, such that
we can turn colorization off in that case as well.
This commit reworks the unit tests such that all three classes
(Redis, RedisArray, and RedisCluster) can be tested using the
TestRedis.php script.
Now, when running TestRedis.php an option can be passed for which
part of phpredis we would like to test (defaults to Redis).
