Rate-limiting plugin doesn't work properly

[ShinEDL]

Summary

I created a rate-limiting plugin which limit by consumer and set policy to "redis", but it doesn't work properly.

Steps To Reproduce

1.Create a api named "api_test"
2.Create a consumer named "consumer_test" and add a key of key-auth for it.
3.Create a key-auth plugin apply to "api_test".
4.Create a rate-limiting plugin which apply to "consumer_test" and "api_test", set policy to "redis".

some configuration:
config.minute = 1
config.redis_database = 1
config.limit_by = consumer
config.policy = redis

Other configuration is default, and redis_host and redis_password is correct.

5.Run two request to "api_test", it can work properly (one proxy, one limited). However, one second later, I run another request to "api_test", it can proxy.

ps: 1. the interval is one minute；
2. redis server can't find the key about rate-limiting.

There was a recent PR that seems related; can you have a look at #2481 and see if this solves your problem?

@p0pr0ck5 At last, I found that if I set redis_database to 0, it work fine.
