Steps to Reproduce

1. Create two plugin_config with the same configuration

/apisix/plugin_configs/1
{"id":"1","plugins":{"limit-count":{"count":3,"key":"remote_addr","policy":"local","rejected_code":503,"time_window":60}}}

/apisix/plugin_configs/2
{"id":"2","plugins":{"limit-count":{"count":3,"key":"remote_addr","policy":"local","rejected_code":503,"time_window":60}}}

2. Create two routes, each using a different plugin_config

/apisix/routes/1
{"id":"1","plugin_config_id":"1","upstream_id":"1","uris":["/get"]}

/apisix/routes/2
{"id":"2","plugin_config_id":"2","upstream_id":"2","uris":["/anything"]}

4. Visit the route /get and you can see that there are 2 remaining left

curl 127.0.0.1:9080/get -i

...
X-RateLimit-Limit: 3
X-RateLimit-Remaining: 2
...

5. Visit the route /anything, this is only 1 remaining left (should have 2 left)

curl 127.0.0.1:9080/anything -i

...
X-RateLimit-Limit: 3
X-RateLimit-Remaining: 1
...
