   ### Issue description
   
   lua-resty-healthcheck的主动检查如果不能配置最少保留节点数，在出现检查地址出错或者检查接口不通等原因的时候，会把所有节点全部下线，出现灾难性的问题

   - OS (cmd: `uname -a`):centos7
   - OpenResty / Nginx version (cmd: `nginx -V` or `openresty -V`):1.19.9.1
   - etcd version, if have (cmd: run `curl http://127.0.0.1:9090/v1/server_info` to get the info from server-info API):3.4.9
   - apisix-dashboard version, if have:2.7
   - the plugin runner version, if the issue is about a plugin runner (cmd: depended on the kind of runner):

   BTW, the current health check can't bring all the nodes down. See https://github.com/apache/apisix/blob/59497deb8f3d7df2a9bd877d367f62108aea078f/apisix/balancer.lua#L86

   When there is something wrong with the health check, the original nodes will serve as used.
