Bump redis from 4.5.1 to 4.6.0

Bumps redis from 4.5.1 to 4.6.0.

Changelog

Sourced from redis's changelog.

4.6.0

• Deprecate Redis.current.

• Deprecate calling commands on Redis inside Redis#pipelined. See #1059.

  redis.pipelined do
    redis.get("key")
  end

  should be replaced by:

  redis.pipelined do |pipeline|
    pipeline.get("key")
  end

• Deprecate calling commands on Redis inside Redis#multi. See #1059.

  redis.multi do
    redis.get("key")
  end

  should be replaced by:

  redis.multi do |transaction|
    transaction.get("key")
  end

• Deprecate Redis#queue and Redis#commit. See #1059.

• Fix zpopmax and zpopmin when called inside a pipeline. See #1055.

• Redis#synchronize is now private like it should always have been.

• Add Redis.silence_deprecations= to turn off deprecation warnings. If you don't wish to see warnings yet, you can set Redis.silence_deprecations = true. It is however heavily recommended to fix them instead when possible.

• Add Redis.raise_deprecations= to turn deprecation warnings into errors. This makes it easier to identitify the source of deprecated APIs usage. It is recommended to set Redis.raise_deprecations = true in development and test environments.

• Add new options to ZRANGE. See #1053.

• Add ZRANGESTORE command. See #1053.

• Add SCAN support for Redis::Cluster. See #1049.

• Add COPY command. See #1053. See #1048.

• Add ZDIFFSTORE command. See #1046.

• Add ZDIFF command. See #1044.

• Add ZUNION command. See #1042.

• Add HRANDFIELD command. See #1040.
