Expose basic config details for RedisClient

[slai11]

This pull request exposes the basic configuration details on RedisClient via instance methods, referencing the configuration values in available in Redis::Client (https://github.com/redis/redis-rb/blob/2b183addb9175641a48e1d8616772282a31c0532/lib/redis/client.rb#L48-L82).

This should close the gap between the raw RedisClient for sentinels and Redis::Client for standalone Redis. More context can be found in this issue: https://github.com/redis/redis-rb/issues/1231

Thank you!

@casperisfine sorry for the ping on this, but is there a release schedule for fixes in redis-client? I'm guessing this will go out in v0.17.2.

[casperisfine]

Yeah sorry. Can you use a git branch to double check it solves the issue with redis-rb ? Once you have confirmed it I can release both.

I prepared a branch on my fork that uses master branch of this project. https://github.com/slai11/redis-rb/tree/slai11-demo-fix

➜  redis-rb git:(slai11-demo-fix) ✗ bin/console
irb(main):001:0> sentinel = Redis.new({:password=>"password123",:name=>"mymaster", :sentinels=>[{:host=>"localhost", :port=>26480, :password=>"password456"},{:host=>"localhost", :port=>26481, :password=>"password456"},{:host=>"loc
alhost", :port=>26482, :password=>"password456"}]})
=> #<Redis client v5.0.8 for redis://127.0.0.1:6480/0>
irb(main):002:0> sentinel.connection
=> {:host=>"127.0.0.1", :port=>6480, :db=>0, :id=>"redis://127.0.0.1:6480/0", :location=>"127.0.0.1:6480"}
irb(main):003:0> exit

Would that suffice as a check?

0.18.0 is out.
