Bump redis from 4.7.1 to 5.0.0

[dependabot]

Bumps redis from 4.7.1 to 5.0.0.

Changelog

Sourced from redis's changelog.

5.0.0

• Default client timeout decreased from 5 seconds to 1 second.
• Eagerly and strictly cast Integer and Float parameters.
• Allow to call subscribe, unsubscribe, psubscribe and punsubscribe from a subscribed client. See #1131.
• Use MD5 for hashing server nodes in Redis::Distributed. This should improve keys distribution among servers. See #1089.
• Changed sadd and srem to now always return an Integer.
• Added sadd? and srem? which always return a Boolean.
• Added support for IDLE paramter in xpending.
• Cluster support has been moved to a redis-clustering companion gem.
• select no longer record the current database. If the client has to reconnect after select was used, it will reconnect to the original database.
• Better support Float timeout in blocking commands. See #977.
• Redis.new will now raise an error if provided unknown options.
• Removed positional timeout in blocking commands (BLPOP, etc). Timeout now must be passed as an option: r.blpop("key", timeout: 2.5)
• Removed logger option.
• Removed reconnect_delay_max and reconnect_delay, you can pass precise sleep durations to reconnect_attempts instead.
• Require Ruby 2.5+.
• Removed the deprecated queue and commit methods. Use pipelined instead.
• Removed the deprecated Redis::Future#==.
• Removed the deprecated pipelined and multi signature. Commands now MUST be called on the block argument, not the original redis instance.
• Removed Redis.current. You shouldn't assume there is a single global Redis connection, use a connection pool instead, and libaries using Redis should accept a Redis instance (or connection pool) as a config. E.g. MyLibrary.redis = Redis.new(...).
• Removed the synchrony driver.
• Removed Redis.exists_returns_integer, it's now always enabled.

4.8.1

• Automatically reconnect after fork regardless of reconnect_attempts

4.8.0

• Introduce sadd? and srem? as boolean returning versions of sadd and srem.
• Deprecate sadd and srem returning a boolean when called with a single argument. To enable the redis 5.0 behavior you can set Redis.sadd_returns_boolean = false.
• Deprecate passing timeout as a positional argument in blocking commands (brpop, blop, etc).
